提出了具有反馈机制的动力堆诊断的统一理论。根据平稳时间序列数据计算出的相关函数，反馈系统可以用等效的创新模型来表示。从形式上讨论了有条件的反馈系统开环传递函数的可辨识性； (1)最小相位系统，(2)噪声源的独立性。从反馈结构来看，非最小相的性质与反应性为正或零功率反应堆传递函数为超临界有关。在非最小相位和相关噪声源的情况下，在相当于反馈系统的创新模型中可能存在新的附加回路。
A unified theory is presented for diagnosis of power reactors with feedback mechanism. In terms of correlation functions calculated from stationary time series data, a feedback system can be expressed by an equivalent innovation model. From the formalism the identifiability of open loop transfer functions in the feedback system is discussed under conditions; (1) the minimum phase system, (2) the independence of noise sources. From the feedback structure, the property of the nonminimum phase is related to that the reactivity is positive or zero-power reactor transfer function is supercritical. In the case of the nonminimum phase and correlated noise sources, there is a possibility of new additional loops in an innovation model equivalent to the feedback system.
