摘　　要：针对有源电力滤波器(APF)的直流侧电压控制问题,基于传统比例积分(PI)控制方法控制精度低,存在超调和快速性这一矛盾,自抗扰控制(ADRC)因引入干扰补偿,大大提高其抗干扰能力。但目前单一的优化算法整定ADRC参数不能提高控制精度及响应速度,现提出通过改进天牛须算法(BAS)来优化自抗扰控制器参数的方法,将变异环节引入天牛须算法,使其跳出局部搜索,更快搜索得到全局最优解,并提高精度的同时兼顾响应速度,搭建MATLAB/Simulink仿真以及充电桩谐波治理的APF实验平台进行验证,通过实验验证,该算法优化后能够减少超调,实现电流的精确跟踪,其谐波率从3.32%降低到1.34%,证实算法的有效性。Aiming at the DC side voltage control problem of APF of active power filter, the traditional PI control method has the contradiction of low control precision and high speed. Automatic disturbance rejection control(ADRC) greatly improves its anti-interference ability by introducing interference compensation. But at present a single setting ADRC parameter optimization algorithm can not improve the control precision. In order to solve the problem that the BAS algorithm is easy to fall into local optimum, the mutation link is introduced into the algorithm to make it jump out of local search and get the global optimal solution more rapidly. By building MATLAB/Simulink simulation and APF experimental platform to verify that the algorithm optimization can reduce overshoot, achieve accurate current tracking and reduce the harmonic rate that from 3.32% to 1.34%.
