摘　　要：在同步旋转坐标系下,针对永磁同步电机转速调节问题,提出了一种模糊滑模控制器的设计方法,削弱了滑模控制存在的"抖动"现象,具有抗外部扰动和内部参数摄动的鲁棒性。针对速度估计问题,提出了一种自适应滑模观测器法的新型无速度传感器运行的估计方法,节约了成本并增强了系统的可靠性。仿真结果表明:控制系统能够稳定运行,具有良好的动态、稳态性能。In view of the speed regulation problem for PMSMs in the synchronous rotating coordinate,a new method of fuzzy sliding mode controller was designed to reduce chatting aroused by conventional sliding mode control.The result shows that it is robust to external disturbance and interior parameters perturbation.For the speed estimation problem of PMSMs,a novel speed sensorless method was put forward by using the adaptive sliding mode observer,thereby cost is effectively reduced and system＇s reliability is enhanced.Simulation results illustrate the system has a good dynamic and static performance.
