摘要 针对系统模型不确定性和干扰对矢量控制性能的影响,利用Q-参数化理论设计控制器,设计了一种简单有效的感应电机速度控制策略。该速度控制器由鲁棒转子磁链估计器(RRFE)以及参考模型跟踪控制器(RMTC)两个部分构成。RRFE主要用于转子磁链估计,以确保转子磁链获得快速准确的定向,而RMTC则在电机参数发生变化和出现干扰的情况下,获得磁链和转速的渐进跟踪性能。仿真试验结果表明,干扰得到有效抑制,系统具有较好调速性能。 Aiming at the influence of plant model uncertainty and disturbance on the performance of induction motor vector control, by using the Q-parameterization theory for the controller design, a simple and valid speed control strategy is presented. This speed controller consists of a robust rotor flux estimator （RRFE） and a reference model tracking controller （RMTC）. The RRFE is used to provide real-time estimation of the rotor flux to insure fast and exact orientation of rotor flux. The RMTC can asymptotically track the flux reference signal and the rotor speed under parameter uncertainties and disturbances. The simulation results show the disturbance is effectively restrained and the system has excellent speed-adjustable performance.
