摘要
针对PMSM(永磁同步电机)分数阶PI~λ控制器的参数整定,提出了一种频域法与飞蛾火焰优化算法相结合的方法。以永磁同步电机的分数阶模型作为被控对象,首先使用频域法根据系统的相对稳定性和增益变化的鲁棒性等条件得到控制器的方程;然后结合该方程的图像求解出分数阶PI~λ控制器的参数,以该参数为中心位置,指定寻优的范围,进而应用火焰优化算法对其周围进行寻优。仿真和实验结果表明,该分数阶PI~λ控制器能够降低系统的超调量,提高系统的快速跟踪能力和抗干扰能力,具有较强的鲁棒性。
Aiming at parameter tuning of fractional order PI λ controller of PMSM, this paper proposed a method, which combined the frequency-domain method and moths fire optimization algorithm. This paper used the fractional order model of PMSM as the controlled object. Firstly, it used the frequency-domain method, the it obtained the equation of the controller according to the relative stability of the system and the robustness of the gain variation. After that, it solved the parameters of fractional order PI λ controller by combining the image of the equation and optimized these parameters by using moths fire optimization algorithm. The simulation and experiment results show that the fractional order controller can reduce the overshoot of the system, improve the rapidity and anti-interference ability of the system, and has a certain degree of robustness.
