摘要：
Maximum power point tracking and its control procedure steadiness qualification of wind turbines are satisfied by the PSOSMC strategy, which is proposed in this work. In order to achieve the stable control of generator torque, the PSOSMC system model is established based on the PID hyperplane, and the stability of the control system is proved by the Lyapunov principles simultaneously. In this work, the PSOSMC strategy is carried out from the aspects of aerodynamic efficiency, power generation efficiency, generator torque and low-speed shaft torque. The results show that the PSOSMC proposed can improve the power generation efficiency of wind turbines compared with other control strategies. Besides, the fluctuation of torque of the generator and the low-speed shaft reduce significantly. It juggles maximum power conversion and pleasurable operational steadiness of wind turbines. © 2022, Solar Energy Periodical Office Co., Ltd. All right reserved.
