摘要
针对感应电机数学模型的非线性、强耦合特性,应用逆系统理论,将感应电机转矩与定子磁链动态解耦成2个一阶线性子系统,证明感应电机数学模型的可逆性。设计了基于逆系统方法的感应电机闭环控制系统。仿真结果表明这种基于逆系统的交流控制策略具有良好的非线性解耦控制效果和动、静态性能。
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.
