Design and Simulation of a Steam Turbine Generator using Observer Based and LQR Controllers
Abstract
Steam turbine generator is an electromechanical system which converts heat energy to electrical
energy. In this paper, the modelling, design and analysis of a simple steam turbine generator have
done using Matlab/Simulink Toolbox. The open loop system have been analyzed to have an
efficiency of 76.92 %. Observer based & linear quadratic regulator (LQR) controllers have been
designed to improve the generating voltage. Comparison of this two proposed controllers have
been done for increasing the performance improvement to generate a 220 Dc volt. The simulation
result shows that the steam turbine generator with observer based controller has a small percentage
overshoot with minimum settling time than the steam turbine generator with LQR controller and
the open loop system. Finally, the steam turbine generator with observer based controller shows
better improvement in performance than the steam turbine generator with LQR controller.
