Abstract

This research aims to develop a low-cost portable throttle curve manipulator for a smooth initial movement of an electric vehicle. The hardware is mostly made up of an Arduino and a pulse width modulation (PWM)-to- direct current (DC) converter, which can be easily installed in electric vehicle. The manipulator produces a throttle output curve based on the current throttle input. The suitable throttle output curve is investigated in two stages. First, the four throttle curve types are compared based on motor vibration change and total energy usage during initial movement. They are none, linear, exponential, and polynomial curve types with a delay of 1 s. Then, in the second stage, the delay is varied from 0.5 to 2.5 s. The result shows that the linear throttle curve output with a delay of 1 s produces is appropriate to refine the initial movement of an electric vehicle compared to the polynomial and exponential curve types. The brushless DC electric (BLDC) motor vibration change decreases from 148.75 Hz to 107.45 Hz and total energy usage decreases from 90.64 joules to 87.23 joules. Therefore, the research concludes that the low-cost portable throttle curve manipulator can be developed using a linear throttle output curve with a delay of 1 s.

Abstract

Hydroponic cultivation requires rigorous monitoring and control of several parameters, such as turbidity, electric conductivity, acidity (pH), dissolved oxygen and nutrient, which usually be measured once a day manually. Therefore, automation in hydroponic cultivation requires those water quality information as the controlled variable. The dissolved nutrient is especially important because it significantly affects the hydroponic plant growth. Acquiring the dissolved nutrient can be done by using a PPM (parts per million) sensor, but most of the time the sensor needs further processing to obtain the desired measurement. This study presents a reading correction of a PPM sensor based on a regression method so the desired measurement can be done. Sample water with different PPM, such 309 PPM, 290 PPM, 762 PPM, 1910 PPM and 2420 PPM are measured first using a standard PPM meter. Then, the sample PPM is measured by using the PPM sensor. The study also investigates the best regression method to map the PPM sensor measurement to the standard PPM meter measurement by comparing several line equations, such as linear, exponential, polynomial and logarithmic. The function coefficient and bias is chosen by using least square methods. After comparing, the result shows that the polynomial function provides the best reading correction with average error of 76 PPM. The error is especially few when measuring the higher PPM (more than 500 PPM), which is suitable with hydroponic cultivation. Therefore, the PPM sensor with the polynomial function shown in this study can be used to measure the dissolve nutrient accurately in the automation of hydroponic activity compare to other line equations. This study is limited to small sample sizes to prove the concept. The generalization can also be considered in the future study.

Abstract

In conjunction with sustainable development goal 3 (SDG 3), it is important to develop a national electrical component for physiotherapy robot development. This study aimed to develop an open-loop field-oriented control (FOC) driver utilizing BTS7960. The driver utilized three BTS7960s that produce sinewave with variable angular frequency (ω). The research then compared the open-loop FOC driver with electronics speed controller (ESC) performance to drive a brushless DC (BLDC) motor with an initial rotation per minute (RPM) of 400, 500, and 600. The main observation was RPM reduction when the BLDC motor was subjected to loads of 20, 35, 50, 65, and 80 gr. The result showed that the open-loop FOC driver performed better, especially on an 80 gr load. For an initial RPM of 600, the RPM reduced to 100 when controlled with an open-loop FOC driver, but lesser when controlled using ESC. The open-loop FOC driver produces higher torque on the BLDC motor so it could rotate with less reduction compared to ESC, which is evident. The open-loop FOC driver can be easily developed using BTS7960 with a settling time of 4 seconds. However future studies should still consider close-loop FOC drivers to achieve higher torque performance and faster transient response for physiotherapy robot applications.

Abstract

Dalam upaya akselerasi SDG3, maka alat bantu kesehatan seperti Ankle Foot Orthosis (AFO) perlu dikembangkan dengan penambahan aktuator gerak sendi. AFO yang dimodifikasi ini kemudian disebut sebagai robot AFO. Aktuator yang dibutuhkan pada robot AFO harus memiliki capaian torsi yang cukup, tetapi dengan dimensi yang sekecil mungkin agar keseluruhan struktur AFO adalah padu. Ketersediaan aktuator tersebut, seperti motor BLDC, sulit ditemukan di dalam negeri, melainkan motor BLDC dengan dimensi dan capaian torsi kecil saja. Sehingga penelitian ini mengusulkan modifikasi motor BLDC pabrikan BM 5010-360KV untuk meningkatkan capaian torsinya. Urutan kegiatan adalah simulasi komponen utama motor BLDC, modifikasi motor BLDC, dan terakhir validasi performansi motor sebelum dan sesudah modifikasi. Empat jenis motor BLDC yang divalidasi yaitu: motor pabrikan, motor modifikasi stator, motor modifisikasi rotor, dan motor modifikasi stator�rotor. Hasil pengujian putar kemudian menunjukkan bahwa motor dengan modifikasi stator memiliki daya yang lebih kecil daripada motor pabrikan yaitu 7.68 watt dibandingkan dengan 27 watt saat berputar dengan beban 50.5 gram. RPM motor juga menunjukkan bahwa motor dengan modifikasi stator memiliki capaian torsi yang lebih tinggi, di mana RPM motor stator baru adalah RPM 622.2 dan RPM motor pabrikan adalah 180.8 dengan beban yang sama. Sementara itu motor dengan rotor baru tidak dapat berputar sama sekali disebabkan oleh beban rotor baru yang lebih berat dari sebelumnya. Modifikasi stator telah berhasil meningkatkan capaian torsi motor, tapi modifikasi rotor belum berhasil dilakukan pada penelitian ini dan akan menjadi penelitian berikutnya. Modifikasi rotor kedepannya perlu dilakukan dengan mempertimbangkan jenis material untuk meminimalisir beban dari rotor modifikasi.

Abstract

A passive controllable ankle foot orthosis (PICAFO) has been developed to treat foot drop on post-stroke patient by controlling the walking gait passively. PICAFO controls the gait by utilizing a proportional integral (PI) controller with an ankle velocity reference. The PI controller must be tuned before being implemented on PICAFO. However, controller tuning based on experimental trial and error is not suggested since it requires the user to use the untuned PICAFO. Therefore, a simplified walking simulation is developed to tune the PI controller using Simulink of MATLAB software. The simulation mainly consists of several parts, such as PI controller, brake model, ankle torque to velocity transfer function, ankle velocity reference, and constant external torque. The result shows that the PI controller can be tuned accordingly to subject’s body mass index (BMI) and the brake model to meet the system specification. In this case, when the subject’s BMI is 22.2 and the brake maximum torque is 1.938 Nm, the system can control the ankle velocity with settling time less than 20 ms. However, if there is an external torque that is outside the range of brake capacities, then the system cannot do the control task. Therefore, improvement in the brake design is necessary in the future to achieve ankle velocity control within wide range of external torque.

Abstract

Sepeda motor listrik memiliki berbagai kelebihan, seperti mengurangi polusi udara dan polusi suara, nyaman digunakan karena bebas dari getaran mesin, serta biaya kepemilikan yang rendah. Meskipun demikian sepeda motor listrik juga memiliki kekurangan. Salah satu kekurangan sepeda motor listrik adalah harga komponen utama yang masih mahal. Akibat dari harga komponen utama yang mahal ini seringkali kualitas komponen lain dikorbankan untuk menekan harga jual, termasuk peredam kejut/shockbreaker. Penggunaan peredam kejut berkualitas rendah mengakibatkan getaran yang dirasakan pengguna cukup besar hingga mengganggu kenyamanan pengguna. Namun demikian belum dapat dipastikan bahwa sumber masalah getaran tersebut hanyalah dari peredam kejut saja. Ada beberapa kemungkinan lain misalnya struktur rangka, dan posisi baterai. Untuk itu dibutuhkan alat bantu untuk melakukan analisa getaran pada sepeda motor listrik, sehingga dapat diketahui penyebab getaran yang dialami oleh pengguna kendaraan. Pada penelitian ini dibangun VibLab, sebuah aplikasi berbasis Android untuk membantu pengguna sepeda motor listrik melakukan analisa terhadap getaran pada kendaraan miliknya. Aplikasi ini menggunakan accelerometer sebagai sensor getaran, kemudian menghasilkan data arah getaran dan nilai akumulatif akselerasi pada setiap kelompok arah. Android dipilih untuk memperluas jangkauan aplikasi terhadap pengguna karena sebagian besar smartphone yang beredar menggunakan Android sebagai sistem operasinya. VibLab dikembangkan dengan metode agile sederhana dalam beberapa tahapan iterasi. Hasil pengujian menunjukkan aplikasi ini cukup akurat dan bermanfaat dalam membantu analisa getaran pada rangka sepeda motor listrik.

Abstract

The efficiency of control systems in permanent magnet synchronous motors (PMSM) is crucial, especially for applications in physiotherapy robots. Previous studies have demonstrated that an open-loop field-oriented control (FOC) driver using BTS7960 outperforms the commonly used electronic speed controller (ESC). This research addresses the challenge of further improving efficiency by employing a closed-loop FOC driver with the BTS7960. The research methodology involves two main stages. First, a PSIM software simulation of a closed-loop FOC using a proportional integral (PI) controller is conducted. The aim is to determine the P and I parameters that result in the smallest settling time, steady-state error, and overshoot in controlling the PMSM motor's rotation per minute (RPM). The second stage involves hardware implementation with the BTS7960, where the PMSM motor RPM is compared under various loads ranging from 10-gram to 60 gram. RPM results from both open-loop and closed-loop configurations are compared. The results show that the closed-loop FOC driver has improved system transient response compared to the previous open-loop FOC driver, notably reducing the settling time from 2.24 seconds to 1.45 seconds for a 60 gram load. Therefore, this research concludes that a closed-loop configuration with well-tuned PI parameters can deliver better performance compared to open-loop methods, as clearly demonstrated.
