伺服系统速度模式下的无传感研究

永磁同步电机的驱动系统逐渐在各种工业生产场合中应用，对其性能的要求如在较大的速度带宽范围时的动态响应和精确控制也越来越高。然而，在调速范围上，对应用于永磁同步电机运行的无传感矢量控制技术来说仍然是个问题。因此，提出在速度调节上运用弱磁控制和等效控制反馈上构建滑模观测器组合控制方法，达到扩展运行速度范围和提高系统的鲁棒性。

Simulation of Servo System Speed Mode Based on Matlab

Drive system of permanent magnet synchronous motor （PMSM） apply gradually to various industrial production situation. The performance such as the speed of large scope of bandwidth and precise control of dynamic response be required more and more highly. However, about the range of speed, the corresponding for PMSM running with senseless technology vector control is still a problem. Therefore, this is raising adjustable speed and weak magnetic control feedback to constructing the sliding-mode observer. Both of them are combinated to expand control method while the method improves the robustness of system speed range.
