The application of internal model fractional order control in induction motor speed control system

According to the principle of IMC, a fractional-order internal model controller which is exchanged integer order filter for fractional order filter is deduced for induction motor speed control system. This controller contains two adjustable parameters, and the controller parameter setting method is given according to the phase margin method. Then, the algorithm is applied to the experimental platform of induction motor speed control system which is based on TMS320LF2407 DSP. The simulating and experimental results show that the induction motor speed control system can obtained good following performance, nice anti-interference performance and stronger robustness with the controller.
