| 摘 要： | 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。

| Abstract: | A new nonlinear control of integrated function control is proposed and its control law deduced.This new control method can achieve zero voltage regulation of the converter output voltage ,i.e.,the closed loop output voltage remains dynamically unchanged when the supply voltage or load current changes.There is no steady 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 theoretical predictions. |
