Applied approach intelligent technique for speed control of induction machine

This paper presents a comparative study of an indirect field oriented control (IFOC) of induction machine (IM) using an integral-proportional (IP), sliding mode (SMC) and intelligent technique based on a fuzzy logic (FLC) controllers for speed regulation. The traditional integral-proportional controller is sensitive to the load torque disturbances. The fuzzy logic control is a part of intelligent control which contain hard and soft computing. The approach of sliding mode control utilizes discontinuous control laws to drive the system state trajectory into a sliding or switching surface in the state space. The effectiveness of the IP, fuzzy logic and sliding mode controllers was tested under different conditions such as reference speed and load torque disturbances. The simulation results demonstrate that the proposed controllers are better robust than the traditional IP controller.
