摘　　要：根据PTC热敏电阻的电流随温度变化的关系,通过模糊PID的控制方法,利用温度偏差和温度偏差的变化率来实时的调整PID参数,从而可以达到恒流放电的目的。系统仿真结果表明,该控制方法具有动态响应较快、超调量小等特点,具有很好的应用前景。According to the relationship between the temperature of PTC thermistor and the current, the paper focuses on PID parameters through the fuzzy-PID parameter in order to achieve the goal of constant–current discharge by using the rate of temperature departure. The results of the system simulation show that the method has good application prospect with the characteristics of faster dynamic response and small overshoot.
