A sliding mode control strategy for chaos suppression in power systems of arbitrary dimensions
Power systems are prone to chaotic oscillations. Conventional sliding-mode controllers are tightly coupled with system dimensions, and the control law needs to be redesigned once the system order changes. This paper proposes a recursive sliding-mode control method independent of...
