摘　　要：矢量控制策略目前已在交流传动领域获得较广泛的应用,但是由于坐标变换需要精确的转子位置角,通常需要安装位置传感器,提高了系统成本,降低了可靠性。本文在获得扩展反电势模型的基础上,设计了基于平滑切换律的自适应滑模观测器,对内置式永磁同步电机进行位置观测。相比于传统方法本文提出的观测器结构能够有效抑制由滑模引起的抖振现象。仿真结果证明该方法有效。Vector control strategy has been in the field of AC drive wider applications, but due to the coordi- nate transformation requires precise rotor position angle, usually require the installation location sensor, sys- tem cost, reduced reliability. Extended back EMF model based on the design of the switching law based on a smooth adaptive sliding mode observer position observations of built - in permanent magnet synchronous motor. The observer structure compared to the traditional method proposed in this paper can effectively sup- press the chattering caused by sliding mode. The simulation results show that the method is effective.
