“…In the field of wind power generation, the pitch motor in the offshore wind power generation system, as a kind of PMSM, faces a more complex working environment. In order to improve the performance of pitch motors in offshore wind power generation systems, and improve the power efficiency of wind turbines, it is particularly important to improve the design of control systems [1][2][3][4][5][6][7].…”

In order to improve the dynamic performance of the control system, a variable frequency sliding mode non-inductive control strategy based on ESO feedforward compensation was proposed in order to improve the disturbance and jitter problems of pitch motor in offshore wind power generation system. The fast exponential approximation law is designed in the velocity loop, and the integrated sliding surface is adopted, which reduces the steady-state error of the traditional sliding surface and weakens the jitter phenomenon of the moving point on the sliding surface. The traditional sliding mode observer is improved, and the variable cut-off frequency filter is used instead of the low-pass filter in the filtering process to filter the signals of each speed band. At the same time, in order to estimate the disturbances in the system, the LESO is designed to observe and compensate for the unknown disturbances, which improves the robustness of the system. The simulation results show that the control strategy in this paper solves the problems of traditional sliding mode control, which not only shortens the response time of the system, but also significantly improves the anti-disturbance performance of the system, and the overall effect is significantly improved.

In order to improve the response speed and disturbance rejection ability of a permanent magnet synchronous motor (PMSM) in an electromechanical actuator (EMA), a compound sliding mode control (CSMC) is proposed. The CSMC consists of a sliding mode controller with a new reaching law and disturbance observer based on a symmetric S-type function. The stability of the CSMC is analyzed using the Lyapunov stability analysis. The effectiveness of the CSMC is confirmed by the Simulink simulation, and experiments were conducted on a semi-physical platform. The results obtained by comparing the CSMC with the proportional integral (PI) control and traditional sliding mode control show that the CSMC has a faster response and stronger disturbance rejection ability and reduces chattering.
