ELECTRIC GENERATOR CONTROL UNDER HIGH-FREQUENCY MEASUREMENT NOISES

Abstract

The paper considers the problem of robust control of an electric generator with unknown parameters under the effect of external bounded disturbances and the presence of high-frequency measurement noises. It is assumed that only the load angle is available for measurement, but not the rotor speed. The electric generator model is described by a system of third-order differential equations with algebraic coupling equations. The proposed approach based on the separation of the filtering and estimating properties of the control system is used to solve the problem. Unlike existing analogs this scheme gives the possibility to control independently the quality of filtering and the quality of output stabilization. Also it compensates parametric uncertainties and external disturbances with required accuracy that can be reduced by selecting algorithm parameters. The proposed algorithm is easy in implementation and selection of design parameters.
