Research on Fuzzy Prediction Control Technique for Induction Motor

In the control of Induction Motor, great errors will be produced in speed control due to the parameters of the resistance and reactance. Based on the model of Induction Motor, a fuzzy predictive control method for the nonlinear discrete systems was proposed by introducing fuzzy logic system into predictive control strategy, and a high performance speed controller was designed using Fuzzy Predictive control method. By means of the DSP platform, system model could be compiled into real-time code and downloaded to the hardware to implement on line simulation. The experiment results show that the controller has acquired good speed response and high anti-jamming for electromechanical dynamics.
