FULL FUZZY CONTROL OF A DSP-BASED HIGH-PERFORMANCE INDUCTION-MOTOR DRIVE

The DSP implementation of a fully digital high-dynamic performance ind uction motor drive, in which all four controllers are fuzzy controller s, is discussed. The input signals to the space vector PWM modulator a re generated by a control system which incorporates four interacting f uzzy controllers. The design of these fuzzy controllers is also discus sed, and both simulation and experimentally obtained results are given . These are in excellent agreement. It is a major advantage of the fuz zy-controlled system that the development time is significantly reduce d and the need for explicit induction motor drive models is eliminated .
