【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.更多还原
