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.
