传统PID（比例-积分-微分）控制对被控系统的参数摄动比较敏感，滞环控制具有较强的鲁棒性，将滞环PID控制方法引入到以恒流充电的蓄电池充电器中，可以使变换器具有很强的鲁棒性、适应性和稳定性。充电器主电路采用移相全桥变换器，给出了传统PID和滞环PID控制的仿真模型，针对变换器负载波动对输出电流的影响，以及输出电流的稳定性，分别作出了仿真试验和分析。仿真结果表明，将滞环PID控制应用到蓄电池充电器能够获得相对恒定的电流并且使得蓄电池充电器对外部响应及其内部参数的摄动有良好适应性。

Traditional PID control parameters of the controlled system is sensitive to perturbation and the hysteresis control has strong robustness, so applying hysteresis PID control method in the battery charger with constant current charging can make the converter have strong robustness, adaptability and stability. This study uses a phase-shifted full-bridge converter for the main charger circuit, establishing the traditional PID and the hysteresis PID control simulation model. It carries out the simulation analysis for effects of load fluctuations on the converter output current and the stability of the output current. Simulation results show that the application of hysteresis PID control to the battery charger can obtain a relatively constant current and makes external battery charger for the camera and the internal parameters have good adaptability in response to the move.
