摘　　要：对扰动时变的单变量控制系统性能评价方法进行了深入地分析和研究,它的主要思想是根据系统的输出检测扰动的变化,对扰动进行分段处理后再进行评价.另外,针对发电厂过热汽温控制系统的性能评价问题,利用阜新清河门发电厂过热控制系统的实际运行数据,采用扰动时变的单变量控制系统性能评价方法对系统进行了分析研究.通过仿真结果的对比,验证了该方法的有效性.The performance evaluation methods of time-varying single variable control system with disturbances are analyzed and researched,and its main idea is to detect disturbance change of the output of time-varying system,and then the system performance is evaluated after processing section by section.In addition,using performance evaluation methods of single variable control system,the system is analyzed with actual operation data of overheat control system in fuxin qinghemen power plant.By contrast,the simulation results verify the effectiveness of the proposed method.
