In this paper, a proportional plus integral (PI) type sliding surface has been proposed for designing a fuzzy variable structure controller to solve load-frequency control problem in presence of load disturbances. It is shown that the proposed controller is effective and robust enough when the system suffers from mismatched condition but the model uncertainty and disturbance are assumed to be bounded. Furthermore, the proposed control strategy drives the states to the sliding surface and also maintains the sliding motion. To illustrate the approach presented has been tested on load-frequency control of power systems and the analytical claims have been justified under the uncertainty involved in the load demand of inter-connected power systems.
