The text proposes a control method which is based on genetic algorithm improved PID control ac-cording to the traditional PID control, which takes crystal brake tube switching capacitor （TSC） as the research object. The method can optimize the control parameters and make the system transient response and control per-formance to achieve the best results. The simulation and experimental results verify that the proposed control method has strong robustness and adaptability, which also can improve the accuracy of compensation of the TSC System and effectively improve the quality of power supply.
