The application discloses a layered processing method for plate-shaped dispersion fuel elements and belongs to the technical field of nuclear reactor physics analysis. The method is aimed at solving the power distortion problem of the existing reactivity equivalent physical conversion method used for plate-shaped fuel elements. The method first calculates the initial effective multiplication factor of a double non-uniform system containing poison and fuel particles, and the system containing only fuel particles after removing the poison; then sets the layer number n, divides the fuel particles equally and symmetrically gathers them to each equal line position, and adjusts the material similarity ratio to make the system multiplication factor equal; finally, gathers the poison particles according to the same logic and adjusts the similarity ratio to make the system multiplication factor equal. The application avoids the neutron flux distribution distortion and ensures the rationality of the power distribution through layered equal division and gathering and two-step similarity ratio optimization. Moreover, the application can accurately simulate the particle self-screening effect and realizes high-precision conversion of the double non-uniform system into a single non-uniform system.

The invention discloses a self-adaptive control parameter optimization method for a multi-field industrial control system, and belongs to the technical field of industrial control and intelligent control. Uniform system state representation is constructed by collecting multi-source heterogeneous time series data in a multi-field industrial control system; performing non-intrusive virtual state evolution deduction on the multiple groups of candidate control parameters to generate a corresponding system response track; an optimal parameter verification mechanism based on physical residual errors and parameter risk potential energy is introduced, and parameter combinations which violate physical constraints or have high risks are screened out; based on frequency domain topology gating analysis of spectrum entropy and spectrum geometric gravity center, frequency domain constraint is carried out on stability and safety of control parameters, and application of the control parameters is triggered only when the frequency domain stability condition is met. On the premise that an existing production process is not interfered, safe and steady self-adaptive optimization is carried out on the control parameters of the multi-field industrial control system, and the parameter setting reliability and engineering practicability of the complex industrial control system are improved.
