Full fuzzy control of a DSP-based high performance induction motor drive

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