论文摘要
蒸汽轮机发生器是一种机电系统，将热能转换为电能。在本文中，使用MATLAB/SIMULINK工具箱完成了简单的蒸汽轮机生成器的建模，设计和分析。已经对开路系统进行了分析，其效率为76.92％。基于观察者的和线性二次调节器（LQR）控制器已旨在改善生成电压。对这两个提出的控制器进行了比较，以提高性能改善以产生220 dC伏特。模拟结果表明，与带有LQR控制器和开放环系统的蒸汽轮机发生器相比，具有观察者基于观察者的控制器的蒸汽涡轮机的比例较小，其结算时间最少。最后，具有基于观察者的控制器的蒸汽轮机发生器比带有LQR控制器的蒸汽轮机发电机表现出更好的性能改善。
Steam turbine generator is an electromechanical system which converts heat energy to electrical energy. In this paper, the modeling, 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.
