Continuous finite time control for static var compensator with mismatched disturbances

In this paper, the composite anti-disturbance control problem is addressed for a single machine bus system with static var compensator. A finite time disturbance observer is designed to estimate the external disturbances. Then based on disturbance estimation value, a continuous finite time anti-disturbance controller is proposed. It is proved that the proposed scheme can guarantee that the system outputs converge to zero in finite time. Finally, a simulation result is presented to demonstrate the effectiveness of the developed method.
