| 摘 要： | 针对强磁场实验装置(SHMFF)的链式高压有源电力滤波方案规划，基于有源滤波系统的非线性特性， 采用分数阶值。PI 控制器替代普通PI 控制器，在此基础上引入粒子群算法优化指令电流PI 控制器参数，并通过 实验对比分析了人工整定的PI 控制器与PSO 整定的PI 控制器的运行效果。经样机实验表明，采用的PSO 算法 整定的电流内环控制器是正确的，且具有一定的参考价值。

| Abstract: | According to the scheme of SHMFF chain-type high voltage active power filter (APF), considering the non-linear characteristics of APF, fractional order PI controller was used to instead of ordinary PI controller. On this basis, the introduction of particle swarm optimization command adjusts current PI controller parameters to achieve optimal control of harmonic compensation. Finally, the working effect of PI controller parameter setting by artificial and PI controller parameter setting by PSO is comparative analyzed through simulation and experimental results. The results show that the strategy is correct, and it has a certain reference value. |
