A fuzzy adaptive PID controller with controlled series capacitor compensation (TCSC) is designed to overcome the shortcomings of traditional PID control, and it is robust and improves the control quality. Combining with the inverse system method and the quadratic optimal control theory, the TCSC nonlinear optimal stability controller of a two-machine system is designed. According to the resistance value calculated online by the TCSC nonlinear optimal controller as the command tolerance, the TCSC is allowed to implement the command tolerance by the fuzzy PID controller. The simulation results show that the designed controller effectively dampens the system oscillation and improves the system stability.
