| 摘 要： | 摘要：基于MATLAB平台，以Buck型电路为对象，在MATLAB／Simulink中先搭建数学模型，采用改进型继电反馈技术，通过激励电源系统产生极限环振荡，测出原系统参数，根据经验公式，确定补偿电路，最后分析闭环控制系统性能指标．通过与原始Z—N法和适度超调法仿真对比，建立的改进型仿真电路可以实现对Buck型开关电路的PID补偿参数自动整定，达到了较好的设计要求．

| Abstract: | Based on MATLAB platform, and Buck type circuit as target, we first build mathemat- ical models in the MATLAB / Simulink, adopting improved relay feedback technology, through the excitation power system to generate limit cycle oscillations, then measure the parameters of the origi- nal system according to the empirical formula to determine the compensation circuit, finally analyse the closed--loop control system performance. Comparing the simulation of the original Z--N method with that of moderate overshoot method, we achieve the established circuit simulation on PID com- pensatory parameter auto--tuning to Buck switching circuit, which better meet the desired design re- quirements. |
