根据大型火电机组的生产实际，对火电机组的过程控制系统进行分析，设计出原理正确、功能较为全面的300MW火电机组过热汽温控制系统，并利用MATLAB软件对过热汽温控制系统进行仿真。Smith预估补偿控制(According to the actual production of large thermal power units, the process control system of thermal power unit was analyzed, and the superheated steam temperature control system of 300MW thermal power unit with correct principle and comprehensive functions was designed. The superheated steam temperature control system was simulated by MATLAB software.)
