Abstract

Elektro-hidrolik merupakan jenis aktuator yang kompleks dengan ketaklinieran yang tinggi dan mengandung unsur ketidakpastian di dalamnya. Oleh karena itu untuk mendapatkan performa terbaik dari sistem elektro-hidrolik diperlukan pemodelan yang lebih akurat dan sistem pengaturan yang tepat. Tujuan dari tugas akhir ini adalah melakukan pemodelan sistem secara tak-linier dan dilanjutkan dengan perancangan sistem pengaturan tak-linier yang robust untuk sistem elektro-hidrolik. Dalam tulisan ini pemodelan dilakukan dengan menggunakan System Identification Toolbox pada Matlab dari sepasang data input-output yang diambil dari sistem sebenarnya. Model dari sistem ditampilkan dalam bentuk tak-linier, karena mengakomodasi ketaklinieran, ketidakpastian dan gangguan dari sistem elektro-hidrolik. Sistem pengaturan menggunakan Sliding Mode Control (SMC) yang dikombinasikan dengan pengaturan Fuzzy dalam format Adaptif Sliding Mode Control (ASMC) untuk mengkompensasi perubahan parameter, ketaklinieran, ketidakpastian dan gangguan pada pengaturan SMC. Stabilitas sistem pengaturan dijamin dengan fungsi Lyapunov. Hasil pemodelan tak-linier menunjukkan nilai best-fit sebesar 94.65 %. Sementara pengaturan ASMC menghasilkan performa lebih baik dibandingkan dengan pengaturan SMC, hal ini dibuktikan menggunakan metode Sum of Squared Tracking Errors (SSTE) menghasilkan nilai sebesar 0,0121.

Abstract

Kurangnya pemanfaatan modul termoelektrik sebagai pembangkit listrik di masyarakat sering diakibatkan energi yang dihasilkan cenderung tidak stabil.  Sehingga diperlukan sebuah rangkaian penstabil tegangan yang dapat menaik dan menurunkan tegangan menjadi tegangan tertentu. Tujuan proyek ini adalah merancang sebuah rangkaian penstabil tegangan DC skala pico berbasis boost converter. Pengujian dilakukan dengan 3 tahap, yaitu pengujian rangkaian penstabil menggunakan sumber adaptor yang mempunyai tegangan masukan 3-9 V, pengujian kinerja pembangkit termoelektrik pada beberapa ∆T tertentu dan pengujian rangkaian penstabil menggunakan sumber termoelektrik dengan ∆T yang sama dengan pengujian sebelumnya. Hasil pengujian pertama, saat diberikan tegangan masukan 3 hingga 9 V maka menghasilkan tegangan keluaran 5,07 hingga 5,08 V sehingga memiliki persentase ketepatan 98,55% terhadap tegangan 5 V yang diharapkan. Pada pengujian kedua, yaitu saat ∆T bernilai 30, 50 dan 70 °C  menghasilkan tegangan keluaran 2,5, 3,04 dan 3,39 V. Sementara pada pengujian ketiga dengan ∆T yang sama menghasilkan tegangan keluaran 5,08 hingga 5,09 V. Namun, saat ∆T bernilai 12 °C mengeluarkan tegangan 0,8 hingga 0,9 V baik pada pengujian kedua maupun ketiga, hal ini disebabkan tidak memenuhi tegangan kerja sistem penstabil yaitu 2 hingga 24 V. Hubungan antara ∆T terhadap Tegangan Keluaran (V), Arus (I) dan Daya (P) yang dihasilkan memiliki nilai R positif 0,76 hingga 1, yang berarti adanya hubungan berbanding lurus. Sehingga, semakin besar nilai ∆T maka akan berdampak pula pada semakin besarnya nilai V, I dan P yang dapat menjadi indikator kualitas pembangkit termoelektrik yang sedang diuji.

Abstract

Solar energy is energy which can be harnessed conveniently and free. However, its conversion result may not be easily obtained. Based on the previous research, solar power plant is a source of renewable energy, utilizing solar energy. Solar power plant converts solar energy into electricity using Photovoltaic (PV) or solar cells. Even though solar power plant is considered as better energy alternative, it presents problems and weaknesses. In this case, the problems are related to insufficient power generation with low power efficiency, high oscillation and very slow power tracking. Hence, in order to solve these problems, Maximum Power Point Tracking (MPPT) has been utilized. Combination method of P&O-fuzzy and IC-fuzzy is employed to its design. Moreover, combined algorithm may result better power from conventional algorithm due to appropriate performance of duty cycle according to system design, with efficiency result of 79%-85.6%, tracking in searching output power of 0,0055s - 0,008s, low oscillation and maximum power generated by combined algorithm of 1028 watt.

Abstract

Motorcycles are a means of transportation which plays an important role in peoples lives. One of the existing problems on the motorcycle is the indicator system or often called by speedometer, an indicator system showing the value of the volume of fuel oil. In fact, the sensor unit used by the indicator is not a volume sensor but the surface of the fuel sensor in the form of mechanical potentiometers. This equipment irregularly measures oil tank so that the mathematical approach to formulate the relationship between surface height and gasoline volume will be difficult. Therefore, to interpret the data manipulation done by comparison method is the method of comparison experiment and calculation. This method is applied in this research due its more superior accuracy and efficiency. This research designs hardware for monitoring fuel oil based on Radio Frequency Identification (RFID) using AT mega 328 as main controller and LCD to display driver’s identity sent by General Packet Radio Service (GPRS). The sensor used is a buoy sensor, measuring the fuel volume between 0.20 liters to 9.55 liters. It is known that the comparative method has an average rate of 16.1%, in measuring the fuel volume between 0.20 liters to 3.68 liters. It is known that the comparative method has an average rate of 17.9%. On measuring the fuel volume between 0.20 liters to 3.43 liters, the comparative method having an average rate of 7.2% is employed. Based on the test results, the best comparison method in comparison with the interpolation method with the average rate of smallest 7.2% is determined.

Abstract

Keandalan sistem tenaga listrik merupakan salah satu isu utama dalam penyaluran energi listrik. Gangguan berulang pada jaringan distribusi energi listrik sangat mempengaruhi keandalan sistem distribusi. Tujuan dari studi ini adalah meningkatkan keandalan sistem distribusi tenaga listrik dengan melakukukan pemasangan recloser pada jaringan distribusi. Recloser merupakan pengaman yang berfungsi untuk memisahkan daerah yang terganggu sehingga dapat memperkecil daerah yang terdampak gangguan. Pada Penyulang Olak Alen terdapat 2 buah  recloser  yang terpasang pada bus 5 dan 6 dengan indeks keandalan SAIDI 6,0544 jam/tahun dan SAIFI sebesar 1,8724 gangguan/tahun berdasarkan data pada tahun 2019. Pada penelitian ini posisi recloser dioptimalkan dengan algoritma differential evolution (DE) agar keandalan sistem distribusi lebih baik. Berdasarkan simulasi, penempatan recloser  untuk 2 buah recloser terletak pada bus 5 dan 13 dengan indeks keandalan SAIDI 4,5461 jam/tahun dan SAIFI 1,3904 gangguan/tahun. Penempatan posisi  recloser  saat 3 buah terletak pada bus 8, 13 dan 21 dengan indeks keandalan SAIDI 4,0095 jam/tahun dan SAIFI 1,2272 gangguan/tahun. Dari hasil studi tersebut disimpulkan bahwa penempatan recloser menggunakan algoritma DE lebih optimal dibandingkan cara konvensional. Kemudian, semakin banyak recloser yang dipasang, maka keandalan sistem distribusi akan semakin meningkat.

Abstract

This paper presents the design of the modified sliding mode controller (MSMC) for the purpose of tracking the nonlinear system with mismatched disturbance. Provided that the performance of the designed controller depends on the value of control parameters, gravitational search algorithm (GSA), and particle swarm optimization (PSO) techniques are used to optimize these parameters in order to achieve a predefined system’s performance. In respect of system’s performance, it is evaluated based on the tracking error present between reference inputs transferred to the system and the system output. This is followed by verification of the efficiency of the designed controller in simulation environment under various values, with and without the inclusion of external disturbance. It can be seen from the simulation results that the MSMC with PSO exhibits a better performance in comparison to the performance of the similar controller with GSA in terms of output response and tracking error.

Abstract

Particle swarm optimization (PSO) is an optimization algorithm that is simple and reliable to complete optimization. The balance between exploration and exploitation of PSO searching characteristics is maintained by inertia weight. Since this parameter has been introduced, there have been several different strategies to determine the inertia weight during a train of the run. This paper describes the method of adjusting the inertia weights using fuzzy signatures called signature PSO. Some parameters were used as a fuzzy signature variable to represent the particle situation in a run. The implementation to solve the tuning problem of linear quadratic regulator (LQR) control parameters is also presented in this paper. Another weight adjustment strategy is also used as a comparison in performance evaluation using an integral time absolute error (ITAE). Experimental results show that signature PSO was able to give a good approximation to the optimum control parameters of LQR in this case.
