Beschreibung
Zusammenfassung:	The invention provides a DC-DC converter control method and device, a terminal and a storage medium. The method comprises the following steps: acquiring an input voltage value and an output power value of the DC-DC converter; determining a compensation value according to the input voltage value and the output power value; compensating an output value of the PID system by adopting the compensation value to obtain a target value of the PID system; and controlling the DC-DC converter according to the target value. According to the DC-DC converter, the dynamic performance of the DC-DC converter can be effectively improved, and the problems of overshoot and oscillation are avoided. 本发明提供一种DC-DC变换器的控制方法、装置、终端及存储介质。该方法包括：获取DC-DC变换器的输入电压值和输出功率值；根据输入电压值和输出功率值，确定补偿值；采用补偿值对PID系统的输出值进行补偿，得到PID系统的目标值；根据目标值对DC-DC变换器进行控制。本发明能够有效提高DC-DC变换器的动态性能，避免发生超调、震荡的问题。
