ABSTRACT
This paper presents a compact embedded fuzzy system for three-phase induction motor scalar speed control. The control strategy consists of keeping constant the voltage frequency ratio of the induction motor supply source. The control strategy taking the reference speed varies from 500rpm to I000rpm. The response of the fuzzy controller is taken with varying load and speed. And also the fuzzy control system is built in a PIC Microcontroller, which uses speed error and speed error variation to change both fundamental voltage amplitude and frequency of a sinusoidal pulse-width modulation inverter. The controller performance in relation to reference and load torque variations is evaluated by experimental results
