摘要：
A new nonlinear control of integrated function control is proposed and its control law is 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.
