摘要
以Buck变换器为例将状态空间设计方法应用于DC/DC变换器的控制,设计了基于极点配置和二次型最优的DC/DC变换器反馈控制器。MATLAB软件的应用使得整个设计过程简捷、实用。利用Simulink和Power system工具箱对所设计的系统进行了仿真。研究结果表明,Buck变换器通过极点配置和二次型最优反馈控制策略,比使用传统的PI控制具有更好的动态响应调节和稳态误差调节特性,超调量、调节时间等都得到明显改善。
Using Buck converter as an example, the state space design method is applied to the control of DC/DC converter, and the feedback controllers of Buck converter are designed based on the pole placement and the quadratic form optimal feedback control. The application of MATLAB makes the whole design simple and practical. The systems are simulated by using Simulink and Power System toolboxes. The research results show that the pole placement and the quadratic form optimal feedback control methods are superior to the conventional PI control method in steady and dynamic regulating characteristics. The overshoot and the settling time of Buck converter are improved clearly.
