Abstract:In response to the problems of strong coupling, nonlinearity, and poor anti-interference ability in the control system of the rare earth permanent magnet synchronous motor (REPMSM), this paper proposes an active disturbance rejection control method for the REPMSM based on genetic particle swarm optimization (GAPSO). The first step is to introduce the research background and derive the mathematical expression of the REPMSM. In the second step, the mathematical expression of ADRC is derived by designing tracking differentiator, extended state observer and nonlinear state error feedback, and the genetic particle swarm optimization algorithm is used to optimize it. The third step is to discuss the speed performance of the REPMSM based on GAPSO and active disturbance rejection control. The effectiveness of the above methods was verified through Simulink simulation, indicating that the active disturbance rejection control method designed in this paper has a promoting effect on improving motor performance.
