基于快速非奇异终端滑模控制的矿用PMSM控制研究

Research on Mine PMSM Control Based on Fast Nonsingular Terminal Sliding Mode Control

为了提高矿用永磁同步电机(PMSM)调速系统的控制性能,利用滑模控制的优良特性,提出了一种适用于永磁同步电机的快速非奇异终端滑模控制器。构建了可在有限时间内快速收敛的快速非奇异终端滑模面,并避免了终端滑模面的奇异问题。在此基础上设计了一种新型永磁同步电机调速系统。

In order to improve the control performance of permanent magnet synchronous motor （PMSM） speed control system, proposed a fast nonsingular sliding mode control strategy. A fast nonsingular terminal sliding-mode surface with fast convergence in a finite time is built, and the singular problem of the terminal sliding mode surface is avoided. In the last, a novel speed controller is employed by fast nonsingular terminal sliding-mode surface, compared with traditional PI controller.
