Steam turbine generator is an electromechanical system which converts heat energy to electricalenergy. In this paper, the modelling, design and analysis of a simple steam turbine generator havedone using Matlab/Simulink Toolbox. The open loop system have been analyzed to have anefficiency of 76.92 %. Observer based & linear quadratic regulator (LQR) controllers have beendesigned to improve the generating voltage. Comparison of this two proposed controllers havebeen done for increasing the

The simulationresult shows that the steam turbine generator with observer based controller has a small percentageovershoot with minimum settling time than the steam turbine generator with LQR controller andthe open loop system. Finally, the steam turbine generator with observer based controller showsbetter improvement in performance than the steam turbine generator with LQR controller.
