| Abstract: | Aiming at nonlinear and strong coupling features,induction motor mathematical model is decoupled into torque linear subsystem and stator flux linkage linear subsystem by inverse system theory.The paper analyzes mathematical model reversibility of induction motor and designs a closed-loop control system based on inverse system control strategy.The simulation results indicate that control arithmetic has good nonlinear decoupling effect and dynamic-static performance. |
