Design for TCSC fuzzy immunity PID impedance controller

In this paper designs a TCSC fuzzy PID impedance controller, according to TCSC current capacitance error and change rate for erroneous, used the dynamic regulation PID parameter for fuzzy inference system, which has overcome the insufficiency for conventional PID control, strong the robustness and enhance the control quality. And, by joins the immunity feedback element, further proposed the control mode for TCSC fuzzy immunity PID impedance. Simulation results had proven that this algorithm response to various impedance step command, has a smaller over modulation, quicker speed for response and better track performance, basically has realized the system´s no corresponding control.
