V/f SPWM Inverter for Single-phase Induction Motor Contrller Using Adaptive Neuro-Fuzzy Inference System

Abstract

In this paper shows the speed control of a single-phase induction motor using an SPWM inverter. Motor speed can change as the load changes on the motor. Unstable motor speed can cause interference with the system. Control is needed so that the motor can rotate at the rpm set point. For the speed control method used is a constant V / f. This method has the advantage of being able to stabilize the torque produced by the motor with a load correction on the motor. Torque is affected by fluxes produced by the stator. By maintaining the voltage and frequency ratio of the stator, the motor can maintain speed at the rpm set point. In this paper, the control method used is the Adaptive Neuro-Fuzzy Inference System (ANFIS). So that the voltage and frequency ratio of the stator is kept constant with ANFIS control to get a stable speed according to the set point. For the validation of the results, a single phase induction motor with 250 watts of power is tested. Based on the test results, when the system is given a disturbance, the control can return at the set point speed with 0.4 seconds
