Robust controller for synchronous generator with local load via VSC

Abstract

Various robust control techniques, such as integral-block, sliding-mode, and H-infinity controls, are combined to design a controller, forcing an electrohydraulic actuator which is driven by a servovalve to track a chaotic reference trajectory. This approach enables one to compensate the inherent nonlinearities of the actuator and reject matched external disturbances and attenuate mismatched external disturbances. The capabilities of the approach are illustrated in a simulation study.

Utkin, V.I.",,"2007",,"The objective of this paper is to design a nonlinear observer-based excitation controller for power system comprising a single synchronous generator connected to an infinite bus with local load. The controller proposed is based on the using first singular perturbation systems concepts and then Sliding Mode Control technique combining with Block Control Principle. To reduce "chattering" a nonlinear observer with estimation of the mechanical torque and rotor fluxes is designed. This combined approach enables to compensate the inherent nonlinearities of the generator and to reject external disturbances. " 2006 Elsevier Ltd. All rights reserved.
