基于卷尾猴搜索算法的永磁同步电机速度控制系统

Speed Control System of Permanent Magnet Synchronous Motor Based on Capuchin Search Algorithm

针对永磁同步电机(Permanent magnetic synchronous motor, PMSM)在工业应用中抗扰动能力不足的问题,提出一种卷尾猴搜索算法(Capuchin search algorithm, CapSA)用于优化线性自抗扰控制器(Linear active disturbance rejection control, LADRC)参数(CapSA-LADRC)。采用LADRC控制器替代PI控制器;利用CapSA算法整定LADRC参数,使其超调明显减小、抗扰动能力增强、系统稳定性增强;通过Matlab仿真对比分析PI控制器、LADRC控制器、CapSA-LADRC控制器的控制效果。仿真结果验证了CapSA-LADRC的收敛性和有效性。

Aiming at the problem of insufficient perturbation resistance of permanent magnetic synchronous motor(PMSM)in industrial applications,Capuchin search algorithm(CapSA)is proposed to optimize the parameters of linear active disturbance rejection control(LADRC),called CapSA-LADRC.LADRC controller is used to replace the PI controller;The parameters of the LADRC are tuned by using CapSA algorithm,so that its overshooting significantly reduced,disturbance immunity increased,and the stability of the system enhanced;PI controller is comparatively analyzed through Matlab simulation,LADRC controller and CapSA-LADRC controller through Matlab simulation.Simulation results verify the convergence and effectiveness of CapSA-LADRC.
