摘要：针对永磁同步电动机无传感器系统运行，对系统的控制方法进行优化。同时，利用非奇异终端滑模观测器替代传统的滑模观测器，改进了原有滑模观测器，在引入非奇异终端滑模观测器控制系统中，经过程估算反电动势来推算出转子的速度和位置，使系统达到无传感器控制的目的。通过仿真和实验的方法，新型滑模观测器的调速系统能够获得更高的估算精度和更好的动态性能。

Abstract:The control system to optimize the method, for sensorless PMSM system operation. At the same time, the use of nonsingular terminal sliding mode observer instead of the traditional sliding mode observer, to improve the original sliding mode observer, the introduction of nonsingular terminal sliding mode observer control system, the process used to calculate the estimated backEMF rotor speed and position, allowing the system to achieve the purpose of sensorless control. Through simulation and experimental methods, the new sliding mode observer speed control system can achieve higher estimation accuracy and better dynamic performance.
