Abstract: To mitigate the impact of unmodeled dynamics and parametric uncertainties on the stability of the surface permanent magnet rectifier generation system (SPMRS),and address the issues of phase lag and control chatering inherent in traditional sliding mode observers, a novel speed observation method, namely super-twisting optimal L2 gain control (ST-OP-L2C), is proposed. This method employs k -class function-basedsuper-twisting state observation and convex optimization linear matrix inequality solutions.To verify the effectiveness of the proposed method and compare it with traditional sliding mode observer proportionalintegral control,model simulationsand prototype testing experimentswere conducted under varying load power conditions.Simulation results demonstrate that,compared to traditional sliding mode observers,the super-twisting state observer with a k-classfunction can reduce the speed estimation error by more than (204号 2r/min. ,and ST-OP-L2C can significantly decrease the overshoot of the rectifier voltage and electromagnetic torque response.Testing results indicate that the prototype can ensure that the rectifier voltage ripple remains below 0.5% .When the load suddenly changes,itcan achieve stable output of the rectifier voltage within 0.2 seconds with minimal overshoot, efectively enhancing the quality of the system's power supply.
