摘要

开关模式dc-dc变换器的控制采用不同的方法，并且总是要求低成本和简单的设计，这是大多数工业和高性能应用所需要的。本文的主要目的是设计一个控制系统来控制降压型DC- DC变换器的动态行为。采用平均状态空间技术进行建模，并采用状态反馈控制器。采用线性二次型调节器(LQR)技术设计了带有整数积分器和分数积分器的状态反馈控制器(SFC)。对两种控制结构进行了比较，仿真结果表明了分式控制器的有效性。

Design of State Feedback Controller with Integer Integrator and Fractional Integrator for Control of Buck Converter

Control of switch mode dc-dc converters are done using different methods and always the demand is low cost and simple design which is required for most industrial and high performance applications. The main aim of this paper is to design a control system to control the dynamic behavior of the buck DC- DC converter. Average state space technique is used for modeling and state feedback controller is employed. The State Feedback controller(SFC) is designed with integer integrator and fractional integrator using Linear Quadratic Regulator(LQR) technique. Both the control structure are compared and the simulation results show that the effectiveness of the fractional controller.
