摘要
为提高静变电源输出电压的质量,研究了一种自整定模糊PID控制方法。该方法将模糊控制优良的动态性能、灵活的控制特性和PID稳态控制性能的优势相结合,实时地对系统控制量进行调整。在Matlab/Simulink环境下,对于模糊PID和常规PID在静变电源控制中的应用分别进行了仿真。仿真结果表明,模糊PID控制器减少了超调量,抗干扰性和鲁棒性强,系统的动态、稳态性能得到了很大程度的提高。
This article proposed the Fuzzy PID controller plan to increase the quality of the single phase static inverter output voltage, this plan has both fuzzy control good dynamic performance control of flexible and steady performance advantages of PID con- trol, so it can improve the performance of the system, real-time makes the online adjustment to the system control measures. Based on Matlab/Simulink, the system was simulated under the circumstance of the static inverter. Compared with the PID control, the analysis of the fuzzy PID controller simulation results showed that the overshoot was reduced, the quality of anti-interference and robust were enhanced, the dynamic performance of the system has greatly improved, and its steady performance is also better.
