摘　　要：引入逻辑开关函数建立了静止无功发生器的动态数学模型。根据该数学模型的非线性特性,提出了基于TS模型的PID模糊控制方法。对常规PID控制和TS-PID控制进行了理论研究。结果表明:采用TS模型的模糊PID控制比常规PID控制具有更大范围的鲁棒性与稳定性。用Matlab对系统进行了仿真,仿真结果表明利用TS-PID控制器控制静止无功发生器的无功电流具有可行性与有效性。In this paper, logic switch function is introduced, and the dynamic mathematic model of SVG is established. According to the nonlinear character of SVG mathematic model, SVG based on fuzzy control of TS-PID is proposed. By comparing normal PID control with TS-PID fuzzy control, the two control methods are studied in theory. Results indicates that compared with the normal PID, using TS-PID fuzzy control has wider robustness and stability, and according to Matlab/Simulink, controlling reactive current of SVG based on TS-PID fuzzy control has feasibility and validity.
