非线性PID控制与TD跟踪微分器在buck-boost变换器中的应用：稳定输出电压的仿真研究,Buck-Boost变换器的非线性PID控制策略与电路仿真研究,buck-boost变器的非线性PID控制，主电路也可以成别的电路。在经典PID中引入了两个TD非线性跟踪微分器，构成了非线性PID控制器。当TD的输入为方波时，TD的输出，跟踪方波信号也没有超调，仿真波形如下所示。输入电压由20V逐渐变化到35V，设置输出参考电压为10V，在非线性PID的控制下，输出很快为10V，且没有超调，输入电压变化时输出电压也一直稳定在参考值。当输入电压变化时，输出电压也一直为10V。整个仿真主要部分采用S-function，主要包括非线性微分跟踪器以及非线性PID。,buck-boost变换器;
