Discrete Fast-Super-Twisting Sliding-Mode Voltage Control Method for HSPMSG

In this paper, a discrete fast-super-twisting (DFS-STW) voltage controller for high-speed permanent magnet synchronous generators is studied to improve the anti-disturbance capability of the system. On one hand, by introducing a power term into the conventional STW, the convergence of the system is accelerated and the dynamic response of the voltage controller is further improved. On the other hand, it has been discretized to meet the needs of the digital control system. The effectiveness of the proposed control strategy is verified by simulation and experiment, and compared with the traditional control methods.
