摘　　要：针对稳态强磁场超导磁体装置的链式高压有源电力滤波方案规划,提出一种三级电容均压控制方法,并基于有源滤波系统的非线性特性,采用分数阶PI控制器代替普通PI控制器;基于改进的Oustaloup算法,完成分数阶积分的求解。通过仿真与实验对比分析了分数阶PI与常规PI控制器的运行效果,经仿真和实验均表明直流均压控制策略是可行的。Aiming at the program planning for chained high-voltage active power filter system in superconducting magnet power of stabilized intense magnetic fields, combing with the non-linear characteristics of active power filter system, a method adopting the fractional-order PI controller instead of ordinary PI controller was proposed to realize three capacitive equalizing control method, and based on the improved Oustaloup algorithm, the solution of fractional calculus was achieved. Through simulation and experimental comparison, the running effects of fractional-order PI controller and conventional PI controller was analyzed. According to simulation and experiment, this fractional-order PI controller is correct.
