Sliding Mode Control for the Dual-Excited and Steam-Valving Control of Synchronous Generator

Abstract:

Based on the sliding mode control (SMC) technique, a design of the sliding surface for the dual-excited and steam-valving control of the synchronous generators with matched and mismatched perturbations is proposed in this paper. By utilizing some constant gains designed in the sliding surface function, not only are the mismatched perturbations overcomed during the sliding mode, but also the property of asymptotical stability of the rotor angle and the voltage is achieved at the same time. Simulations have demonstrated that the control scheme is robust against the disturbances.
