| Abstract: | The paper uses variable structure control (VSC)theory to analyze and design fuzzy speed controller for induction motor field oriented drive system.A method of adding a switching line feedforward term to the output of fuzzy controller to form a fuzzy linear compound controller is put forward based on the above analysis Experiment results demonstrate that the compound controller obtains the robustness of fuzzy control but also reduces the torque ripple and steady state error as well as acquires fast transition of speed response It is a highly advisable control alternative when both high precision and fast response are demanded |
