A self-adaptive self disturbance rejection control strategy combining self disturbance rejection control strategy and deep deterministic strategy is designed to address the issues of insufficient stability and strong fluctuation of DC bus voltage in the rectification process of green building electrical systems using wind power as the energy source during installation and management due to wind power fluctuations.Establish a mathematical model for the rectification process in green building electrical systems based on the topology of the rectification process,and design an observer to estimate the interference in the system.Design an error feedback law to compensate for the disturbance and improve the system's immunity,thereby suppressing the fluctuation phenomenon of DC bus voltage.Introducing a deep deterministic strategy to adaptively tune the feedback coefficients in self disturbance rejection control,forming an adaptive self disturbance rejection control that has optimal parameters in both transient and steady-state conditions,thereby improving the stability of DC bus voltage.Finally,an experimental model of the rectification section of the green building electrical system was built on the MATLAB/Simulink digital simulation experimental platform,and compared with other control strategies under the same operating conditions to verify the correctness and superiority of the proposed control strategy.
