【Abstract】 According to the induction motor which is the more variable,nonlinear and strongly coupled control target,using the inverse system control strategy,the paper proposes the dynamic inverse system of induction motor speed regulation system.And with the original system,the inverse system constitutes a pseudo linear composite system.In order to realize the high precision control of induction motor speed,the paper designs torque and magnetic flux controllers based on the internal model control theory.Simulation and experimental results show that the system not only has excellent static and dynamic performance but also has strong robustness to the load disturbances and parameter perturbation.更多还原
