摘　　要：基于自适应主动控制,提出一种鲁棒控制方法,通过估计不确定性系统参数的上、下界限,设计自适应主动控制器.同时,给出具体的理论推导及稳定性分析.该方法可以有效消除系统参数扰动的影响,从而实现使永磁同步电机各状态变量能被镇定到任意点,以及输出能渐近跟踪任意期望轨道.数值仿真结果验证了方法的有效性及鲁棒性.A robust control method is proposed and the bounds of the uncertain system parameters are estimated based on adaptive active control so that the adaptive active controller could be designed.Meanwhile,the detailed theoretical derivation and stability analysis is given.The control method can effectively eliminate the influence of the system parameters perturbation,and each state of PMSM can be driven to any user-defined point and the outputs can asymptotically track any desired orbit.The results of numerical simulation have shown that the effectiveness and robustness of the proposed control scheme.
