Desain Dan Simulasi Kontrol Kecepatan Motor Induksi Tiga Fasa Menggunakan Pengendali Pi Dengan Teknik Modulasi Svpwm

ABSTRACT
One of the most effective ways of controlling the speed of an induction motor is to control the frequency and voltage of the source. This can be realized by designing an inverter that produces voltages and frequencies that can be controlled. The inverter design in this study uses the SVPWM modulation technique combined with a PI controller with specifications adjusted to the load, is an induction motor at the Electrical Energy Conversion Laboratory, Riau University with a power of 1.1 kW, 380 V, 2-pole. The determination of the PI control constant was carried out using the Fine Tunning method so that Kp = 3.539 and Ki = 9.526 were obtained. Tests were carried out by running simulations in three conditions, namely no load, full load and variable load at a speed of 2800 rpm. The test results show that the use of a PI controller is able to improve the speed response of induction motors, especially eliminating the stady state error, and can accelerate the rise time response of the motor speed by 0.012 s at no-load, and 0.045 s at full load if the rise time analysis is at the same value . So that it can accelerate the motor to reach a peak speed of 0.341 s at no load and 0.124 s at full load. In addition, the use of the PI controller is also able to maintain the setting speed when the load changes when the motor is running. When the motor is working at no load, then given a load of 3.75 Nm, the motor experiences a speed drop of 57 rpm and takes 2.8 seconds to return to the setting speed of 2800 rpm. then when the load is reduced by 1.875 Nm, the motor increases in speed by 30 rpm and takes 2.7 seconds to return to the setting speed of 2800 rpm.
