摘要

静止无功发生器（SVG）是一种多变量、强耦合的非线性时变系统

采用传统的PI控制方法

其动态性能容易受到自身参数以及外界条件变化的影响

进而影响控制效果。本文提出一种基于模糊PI的变论域自适应控制策略

采用变论域模糊控制实现对外界条件变化的自动感知与调整

将其应用到SVG控制系统的电压外环当中

实现外环控制参数的自适应与自调整。最后在Matlab/Simulink上建立仿真模型进行仿真验证

将该控制策略的控制效果与传统PI、模糊PI控制效果进行仿真对比

通过对比可以看到

本文所提出的控制策略具有动态响应快、抗干扰能力强等特点。

Abstract

Static var generator（SVG）is a multivariable

strongly coupled nonlinear time-varying system and its dynamic performance can be affected by changes of its own parameters and external conditions by the traditional PI control method and

the control result is affected. In this paper

a kind of variable universe adaptive fuzzy control strategy

based on PI is proposed to achieve automatic perception and adjustment to the external condition by the use of variable universe adaptive fuzzy control. It is used in voltage loop of SVG control system so to realize adaptive and self-adjustment of loop control parameter.Finally

the simulation model is set upon Matlab/Simulink for simulation and verification. The control result by the control strategy and that of traditional PI and fuzzy PI is simulated and compared

showing that the new control strategy proposed in this paper has such features as fast dynamic response and strong anti-interference capability.
