针对线性滑模控制永磁同步电机不能实现有限时间控制以及终端滑模控制不能实现快速收敛的问题,提出了一种改进快速终端滑模控制方法。所提控制方法经理论证明能实现更快的收敛速度。滑模控制律通过Lyapunov稳定性定理计算得出。对所提方法进行了仿真验证,并与终端滑模控制作对比,结果证明了所提改进快速终端滑模控制能有效地提高系统的起动性能和抗扰动性能。

[Abstract]
An improved fast terminal sliding mode control method for permanent magnet synchronous motor was proposed. Different from the traditional sliding mode control and terminal sliding mode control methods, finite time control and fast convergence could be achieved by the proposed control method. The control law of the proposed controller was designed according to Lyapunov stability theorem. Simulation results demonstrated that the proposed improved fast terminal sliding mode control method could enhance the starting performance and disturbance rejection ability effectively.
