Design of a controller for operating Diesel Generator to supply isolated loads

The control of voltage and frequency of Diesel Generator (DG) is a challenging task. Fast control actions are required to tackle this propblem. This paper presents a proposed technique to choose the best variable to control the whole system since the whole system is multi-input multi-output. A complete non linear model of DG system is developed for simulation study. The system performance of the open loop, conventional controller and optimal controller are analyzed in a comparitive study.
