单相逆变电源具有较强的非线性和参数时变性,当系统参数摄动或有外部扰动时,传统的数字PID控制器不能达到理想的控制效果,输出电压的波形畸变甚为严重。为此,提出以模糊规则调整PID参数的控制策略,提高PID参数的自适应能力,并在Matlab/Simulin环境下进行仿真。该方式综合了模糊控制和PID控制控制的两种优点,提高了单相逆变电源输出电压波形的质量,抗干扰性和鲁棒性强,减少了超调量,使系统具有良好的动、静态性能。

This article proposed the Fuzzy PID controller plan to increase the quality of the single phase Static Inverter output voltage, this plan unifies the fuzzy control and the PID control’s superiority, real-time makes the online adjustment to the PID parameters. Based on Matlab/Simulink, the system was simulated under the circumstance of the single phase Static Inverter. Compare 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, and it also could be applied on nonlinear systems.
