摘要

本文研究了一种由滑模控制器控制的二次型升压变换器，该变换器属于串级升压系列。在级联升压系列中，考虑到电路复杂度和调制器饱和，二次升压变换器是最佳的折衷方案。滑模控制作为一种非线性控制，应用于开关变换器这种本质上是变结构的系统，具有鲁棒性和稳定性。通过李亚普诺夫方法分析了该系统的稳定性。在Simulink模型上对系统的负载调节、线路调节和阶跃响应进行了分析。并与基于PID控制器的系统进行了比较。

Sliding mode controlled quadratic boost converter

This paper deals with a quadratic boost converter which belongs to cascade boost family, controlled by sliding mode controller. In the cascade boost family, quadratic boost converter is the best trade-off when circuit complexity and modulator saturation is considered. Sliding mode control being a nonlinear control results in a robust and stable system when applied to switching converters which are inherently variable structured systems. The stability of this system is analysed through Lyapunov's approach. Analysis is done for load regulation, line regulation and step response of the system on Simulink model. Also these results are compared with that of PID controller based system.
