Abstract
In a power system, the role of a generator voltage regulator is to ensure that the output voltage is maintained within an acceptable threshold. In this paper a voltage regulator is proposed. The design of this regulator is based on both variable structure control theory and a pole assignment technique. The performance of the proposed regulator has been compared to that of the realistic regulator system proposed by the IEEE Committee on Excitation Systems. The results are discussed, and the pertaining recommendations are given.< >
