摘　　要：PI控制器参数的优化对提升永磁同步电机(Permanent Magnet Synchronous Motor,PMSM)系统的响应速度、稳定性与精度至关重要。为改善粒子群优化(Particle Swarm Optimization,PSO)在PI参数调节中的效果,本文采用混沌粒子群优化(Chaotic Particle Swarm Optimization,CPOS)算法对PI参数进行调优,以PMSM矢量控制系统为研究对象,基于CPSO算法设计了速度环PI控制器,CPSO算法通过引入混沌扰动,显著增强了全局搜索能力,避免了PSO算法陷入局部最优解问题,在较少的迭代次数内,CPSO算法获得了最优PI控制器参数。通过MATLAB/Simulink仿真验证其性能,仿真结果表明,与传统调节方法及PSO算法相比,CPSO算法在超调量、上升时间、峰值时间和积分时间绝对误差(Integral of Time-weighted Absolute Error,ITAE)等关键性能指标上具有明显优势,有效提升了PMSM在实际应用中的响应速度、稳定性和控制精度。The optimization of PI controller parameters is crucial for improving the response speed,stability,and accuracy of permanent magnet synchronous motor(PMSM)system.To improve the effectiveness of particle swarm optimization(PSO)in PI parameter tuning,chaotic particle swarm optimization(CPSO)algorithm is used to optimize PI parameters in this paper.Taking PMSM vector control system as the research object,a speed loop PI controller is implemented based on the CPSO algorithm.By introducing chaotic disturbances,the CPSO algorithm significantly enhances its global search capability and avoids the local optimal solution problem of the PSO algorithm.In fewer iterations,the CPSO algorithm obtained the optimal PI controller parameters.Its performance is verified through MATLAB/Simulink simulation.The simulation results show that compared with traditional adjustment methods and PSO algorithm,the CPSO algorithm has significant advantages in key performance indicators such as overshoot,rise time,peak time,and absolute error of integration time(ITAE),which effectively improves the response speed,stability,and control accuracy of PMSM in practical applications.
