Abstract

This research discusses the Proportional-Integral-Resonant (PIR) control system used to regulate a three-phase induction motor, ensuring stability of the speed output and reducing ripple in the DC current output. The study also covers the modulation techniques employed to control the switching of the rectifier using the Space Vector Pulse-Width Modulation (SVPWM) method, where the threephase current and voltage are represented in synchronous rotating coordinates. In this control strategy, a vector control with SVPWM modulation technique is utilized to achieve optimal DC voltage output. To obtain an optimal controller design, parameter gain tuning is performed on the speed, flux, and torque control cascade using the symmetrical optimum method. Simulation testing is carried out using MATLAB/Simulink software to demonstrate the stability of the speed output and the DC current output of the three-phase induction motor. The three-phase induction motor with the PIR controller yields better results compared to the PI controller, achieving a speed of 163.2 rad/s, reaching a steadystate condition within 0.317 seconds, exhibiting overshoot, and a steady-state error of 2.39%. Keywords: Three phase induction motor, PIR controller, Direct Torque Control, symmetrical optimum.

Abstract

Raspberry Pi (Raspi) is a single-board computer (single-board circuit; SBC) that can be used to run office programs, computer games, and as a media player to high-resolution video. The Raspberry Pi has advantages that resemble computers in general, in every way. on the computer functions can also be done with the Raspberry Pi. This paper discusses the application of the raspberry Pi 3b+ as a VHF receiver at a frequency of 136 MHz-174 MHz using RTLSDR R2832U. The author uses Handy-Talkie as a transmitter for FM waves at a VHF frequency (136 MHz-174 MHz). Raspberry Pi 3 implementation with RTL-SDR R2832U to receive FM waves using GNU Radio and GQRX software. The operating system used in this research is Raspberry Pi OS. The results show that the Raspberry Pi device can be used to receive FM waves at the VHF frequency (136 MHz-174 MHz) with SNR 48.7 dB at 136.025 MHz Dipole antenna examined using VNA (Vector Network Analyzer) with length 52.4 cm on each side and linear shape that can receive signal with VSWR 1.48:1 on frequency 136-174 MHz and gain -14.2 dBm on frequency 136 MHz Keywords: Raspberry Pi, RTL-SDR, FM Signal, Software Defined Radio

Abstract

Fuel cell adalah sebuah alat elektrokimia yang dirancang untuk dapat memisahkan ion hidrogen dan oksigen dengan bantuan bahan katalis. Dari hasil reaksi kimia tersebut akan menghasilkan dua bentuk energi yaitu energi panas dan energi listrik. Namun,fuel cell merupakan alat yang mengandung senyawa kimia yang tidak dapat dikontrol pengeluaran maupun masukannya. Oleh karena itu, dibutuhkannya sebuah alat pengontrol berupa pengendali masukan tekanan gas hidrogen yang dapat untuk mengatur proses reaksi kimia dalam fuel cell itu bekerja agar penggunaan dan keluaran tegangan fuel cell dapat sesuai dengankebutuhan beban. Berdasarkan penelitian ini, hasil pengujian diperoleh bahwa pada fuel cell jenis PEM ini memiliki pengaruh apabila tekanan gas hidrogen jauh melebihi dari gas oksigen yang ada di udara sekitar katoda fuel cell maka tegangan keluaran fuel cell akan semakin rendah. Pada hasil pengujian tanpa pengendalian tekanan gas hidrogen diperoleh tegangan tertinggi pada tekanan 1 BAR dan terendah pada tekanan 1,7 BAR dengan variasi tanpa beban yaitu 51,1V & 5,01V; beban resistif 50W yaitu 64,3V & 4,64V; beban resistif 100W yaitu 66,7V & 4,33V; dan beban resistif 150W yaitu 61,2V & 4,29V. Pengendalian tekanan gas hidrogen dapat menghasilkan tegangan keluaran fuel cell yang sedikit lebih stabil pada beban resistif yang rendah (50W) yaitu dengan rata-rata 45,7V namun cenderung menurun apabila tidak dihubungkan dengan beban resistif apapun.

Abstract

The study discusses the three-phase induction motor control response using the proportional-integralresonant control system (PIR) with the purpose of pressing the ripple on the torque output and stabilizing the output at speed. The study uses three-phase induction traction motor specifications of which one of its uses is on high-speed trains. The vector control method used is the dtc method with the svm technique. This study uses a pole placement method for determining the main parameters. Determination of the main parameter pi is determining the pole by comparing the characteristics of the polynomial with the system pole. When you get the desired pole, And it is also a Kp(speed) is 2.78 and Ki (speed) is -52.27. The value of the Kp ( torsi) is 23,661 and the Ki ( torsi) is -47,278 The value of Kp (flux) is 182,53 and Ki (flux) is - 13.3. Simulated testing uses simulink matlab software to show stability of the output speed which also reduces the ripple on the induction motor torque of three fas.3 fasa speed and motor torque with sinus wave load using pear controller generates a better response than with sinus wave load using pi controller. From the test result data that the steady state error value on the pear controller is less than 1.33 %, while the steady state error value on the greater pi controller is 22.48 %. Keywords: Three phase indution motor, PIR controller, Diret Torque Control (DTC), Pole Placement.
