摘　　要：功率控制是保证压水堆安全、稳定和高效运行的关键技术之一,而实现高性能功率控制的基础是完备的测量信息。由于在反应堆测量系统出现故障的情况下无法获取完备的测量信息,因此研究测量信息不完备情况下的反应堆功率控制问题就具有重要的工程意义。本文在核测量系统故障的前提下,提出了利用堆芯冷却剂温度测量信息来重构核功率信息的状态观测器,进而给出了保证输入状态稳定的动态输出反馈压水堆功率控制器,并通过数值仿真验证了该控制器可以提供满意的功率调节性能。Power-level control is one of the key techniques which provide safe, stable and efficient operation for pressurized water reactors （PWRs）, and information completeness is the basis of realizing power-level control. However, due to the fault in measurement system, it is impossible to guarantee information completeness all the time. Therefore, it is necessary study power-level control in case of information incompleteness. In this paper, by assuming the nuclear measurement system is malfunctioning, a new state-observer that can be utilized to reconstruct the nuclear power is firstly proposed. Based upon this observer, a dynamic output feedback control law is given for the power-level regulation of the PWRs. Numerical simulation shows that this newly-built controller can provide satisfactory power-level control performance.
