在典型的DC-DC转换器系统中，当负载变化或输入电压变化时，可以预期转换器的输出将保持不变，但实际上它不会变化，但会受到可控的调节，这基本上是一致的与调整前的状态。转换器中的调节量通常是开关管的占空比。希望调整时间尽可能短，电压变化尽可能小，也就是说，它具有良好的动态和静态性能，因此需要良好的环路设计。通过控制器的设计，抑制了输入电压Vg或负载变化对系统输出电压或电流的影响，从而减少了系统的过冲和响应时间，达到了设计要求。<br>本文采用状态平均法对开关变换器的小信号进行建模，将连续工作模式下开关周期中的变量和电感电流平均，并对相应的开关周期方程进行线性化处理，通过忽略高阶部分可以获得小信号模型。通过建立平均状态模型。

In typical DC-DC converter system, when the load changes or the input voltage changes, it is expected that the output of the converter will remain unchanged, but in fact it will not change, but will have a controlled adjustment, which is basically consistent with the state before adjustment. The amount of adjustment in the converter is generally the duty cycle of the switch tube. It is hoped that the adjustment time will be as short as possible and the voltage change will be as small as possible, that is, it has a good dynamic and static performance, so a good loop design is needed. Through the controller design, the influence of input voltage Vg or load change on the output voltage or current of the system is restrained, so as to reduce the overshoot and response time of the system and meet the design requirements.In this paper, the state averaging method is used to model the small signal of the switching converter, and the variables in a switching period under the continuous mode of operation and inductor current are averaged, and the corresponding switching period equation is linearized, and the small signal model is obtained by ignoring the high-order part. By building an average state model.<br>
