Abstract

This research is reporting a skid adjustment method of an electric vehicle passenger car model by using active brake force control to improve vehicle stability in various driving condition. The presence of skid is determined by comparing the tires rotational speed and the free-rolling speed. The discrepancy of the measured velocities between these sensors indicates the presence of skidding. Further, a two wheels front steering model is used in this work. When the model performing a turning motion, the measured yaw rates Obtained from speed sensors and steering angle sensor can also be used and compared to observe the skidding that indicates either understeer or oversteer. Ackerman calculation is used to investigate the motion of the model. Compensated moment method is used for braking system during the test, such as accelerating, braking, turning and straight cruising. The control system for either simulation or operation test was performed using fuzzy logic controller. The results then were compared and analyzed to show the capability of the controller method to improve the performance of the vehicle model.

Abstract

The rapid development of technology allows human work to be replaced by robot technology. The most frequently used robot in industry is the robot arm. The robot arm can imitate the human arm's characteristics, so it is often used to help humans lift and move goods. With this principle, the robot arm can be used as a weight-lifting robot to aid in calibrating electronic scales. This paper analyzes the control of the DC motor on a weighing-scale lifting robot arm by optimizing the overshoot with PID (Proportional - Integral - Derivative) control. The PID Control test results on the DC motor rotation are stable at 100 rpm with a steady state error of 0%. The system's response to the DC motor has a settling time of 1,26 s and an overshoot of 2%.

Abstract

Motor induksi banyak digunakan di industri, namun dalam penggunaannya motor induksi memiliki hal-hal yang kurang menguntungkan seperti nilai overshoot tinggi, settling time lama saat start dan bila terjadi pembebanan kecepatan motor induksi akan turun. Sliding mode control diperkenalkan dengan mengambil keuntungan dari karakteristik switching inverter untuk mengontrol mesin elektrik yang akan menghasilkan overshoot rendah dan settling time yang pendek dengan bentuk transient dan steady state yang baik. Sliding mode control didesain untuk beroperasi melebihi variable yang sama seperti digunakan pada metode DTC. Untuk meningkatkan performa putaran motor induksi pada kondisi ada gangguan, control putaran dengan sliding mode control akan diuraikan, dimana jenis control ini robust pada saat terjadi gangguan dengan variasi parameter dan torsi beban berubah. DTC digunakan sebagai paramater kontrol, untuk mencari torsi, fluks dan sudut yang nantinya akan digunakan sebagai penyulut inverter. Untuk kecepatan diambil dari kecepatan estimator, error dan delta error kecepatan putar sebagai masukan pada SMC. Hasil dari simulasi kondisi berbeban, saat starting overshootnya 83 rad/s, time settlingnya 0.12s dan time risenya 0.02s. Pada kondisi perubahan beban, respon hampir tidak mengalami perubahan kecepatan atau bisa dikatahkan respon kecepatan stabil bila ada gangguan meskipun terdapat osilasi atau ripple.

Abstract

For instance, the scalar control is a variable regulation of volt per hertz to sets the magnitude scaling of the motor, of course by linearization of two parameters that is voltage and frequency, which sets to a constant ratio for the only concept of scalar control. In contrast, this method has the disadvantages that cannot decrease or increase the speed range from lower voltage of low speed or upper limit voltage of high speed, due to a certain regions are experiencing issues in constant ratio precision because of switch loss. The resulting output signal is not only has a high harmonic which would lead to losses in the form of heat, but is also causes poor performance at low frequency. For investigation, we used simulation using Direct Torque Control or also called DTC. The application of DTC, becoming one of the motor drive method of induction motor, and would produce the efficient power consumption because of switching pattern based on vector voltage. For simulation result, we use the test techniques when unencumbered and when burdened by parameters of rise time value, settling time value, and set point value.

Abstract

The development of electric vehicles (EVs) drives the need for high-voltage ratio DC-DC step-up converters capable of connecting low-voltage battery power sources to electric drive systems and auxiliary systems requiring high voltages. This study proposes a non-isolated ultra step-up converter incorporating a diode–capacitor–inductor (D–C–L) unit at the input and a voltage multiplier cell (VMC) at the output. This topology achieves high voltage gain at low duty cycles while reducing voltage stress on semiconductor devices, enabling the use of lower-rated components and improving overall efficiency. Two control strategies were evaluated: a conventional Proportional–Integral (PI) controller and a PI controller tuned using Particle Swarm Optimization (PSO). MATLAB/Simulink simulations show that the PSO-PI controller outperforms the conventional PI, reducing overshoot from 21.7% to 8.7%, settling time from 227.78 ms to 117.78 ms, and voltage deviation during load changes from ±35 V to ±15 V. Recovery time under disturbances was also shortened from 0.4 s to as low as 0.15 s. These results confirm that PSO-based tuning enhances voltage regulation, transient performance, and robustness, making it a promising solution for ultra step-up converters in EV applications powered by 48 V sources.

Abstract

Monitoring activities are needed if there are symptoms of a disease that require quick action so that the patient's condition does not get worse, for that we need a system that can notify doctors so they can take action. The patient monitoring system in hospitals is generally still carried out conventionally, among others, nurses or doctors come to the patient's room to check on the progress of the patient's condition, this will be a problem, if the number of medical personnel and facilities is insufficient to monitor. Patients who need special attention for patient care, such as monitoring the patient's breathing rate. The use of the internet of things (IOT), as a device that can work without the help of people, can perform tasks and provide easier and real time data, so that they can access output directly. The purpose of this research is to design an inexpensive health monitoring tool based on the Internet of Things (Respiration Parameters) using a piezoelectric sensor and an ESP32 Wi-Fi module. From the results of the module design taken from 10 respondents, obtained that the average measurement high accuracy (17.76 + 0.61) and the average level of stability of the design has a magnitude of 0.4 so that it can be concluded that using a piezoelectric sensor in this series can obtain good accuracy. This the design can be used to monitor a person's respiration in real-time
