| 摘 要： | 在借鉴国内外相关研究的基础上,对感应电动机非线性解耦控制系统的动态性能进行了深入分析.经过分析发现,在非线性解耦控制器的作用下,感应电动机的转速、磁链控制误差及转子磁链估计误差可以指数收敛至零,但负载力矩估计误差只能是渐近有界的.对感应电动机的仿真结果表明,上述理论分析是正确的.

| Abstract: | Dynamic performance of a nonlinear decoupling controller is analyzed for induction motors. According to theoretical analysis,the error of the motor speed and the rotor flux can converge to zero exponentially with a nonlinear decoupling controller,as well as the error of the flux observer. However,the error of the load torque estimator only can be asymptotically bounded. Simulation results of a certain induction motor indicate that theoretical analysis stated above is correct. |
