摘　　要：基于转子磁链定向的动态数学模型,运用非线性解耦线性化理论,设计了非线性解耦控制器抵消定子电流耦合项的影响,实现对定子电流完全解耦。采用调节器典型系统整定方法,设计了转速和电流PI调节器。仿真结果表明,该系统具有良好的稳态和动态性能。Stator current full-decoupling is realized by the method of nonlinear decoupling based on dynamical mathematic model of rotor-field-oriented control, which is applied to design nonlinear decoupling controller for counteracting the influence of stator coupled current. Current and speed PI controllers were designed by representative-system tuning methods. Simulation results showed that this vector control system with PI controllers is able to achieve a good performance of desired dynamic and steady state responses.
