融合了开关变换器脉动和非线性的特点，提出了积分函数控制新策略，实现了输出电压平均值的即时动态控制，即在电源电压与负载电流瞬态或持续扰动下，开关变换器直流输出电压的动态或稳态输出误差为零。以降压型开关变换器为例，计算机仿真和实验验证了新策略的优良特性。

A new nonlinear control of integrated function control is proposed and its cont rol law deduced.This new control method can achieve zero-voltage regulation of the converter output voltage ,i.e.,the closed-loop output voltage remains dynam ically unchanged when the supply voltage or load current changes.There is no ste ady-state error nor dynamic error between the control reference and the average value of the switched variable.Simulations and experiment with a buck converter have demonstrated the robustness of the control strategy and verified the theor etical predictions.
