Comparison of fuzzy logic and PID controllers for TCSC using Matlab

In this paper, a fuzzy logic controller and a PID controller are used to control firing angles of TCSC using Matlab Simulink, Power System Blockset and Fuzzy Logic Toolbox. The graphic interface of Simulink provides a user-friendly environment where the power circuit and control system are represented in the same diagram. The design and testing of TCSC are verified using the Matlab environment. The studied power system is a simple two-bus system with distributed parameter line. The simulation results show that the fuzzy logic controller can generate better dynamic response.
