Abstract :
This work presents a nonlinear control approach to the MIMO system of a current source inverter (CSI) based static synchronous compensator. Here, a nonlinear mathematical model of transmission STATCOM is derived. Then, by input-output feedback linearization, a state feedback control law is obtained by pole placement. The proposed controller provides good transient stability for synchronous generator under transient disturbances. Besides, fuzzy controller is implemented together with feedback linearizing controller to improve the performance. The efficacy of the control strategy is evaluated by digital computer simulation studies. The comparative study of these results with conventional controller establishes the elegance of the proposed control scheme.
