Abstract

Abstract

The identification of the unknown transfer function about controlled object and physical process of the steam generator level control system of Ling’ao Phase II NPP was studied and the identification method was given.The basic data used for the identification were obtained by analyzing the feature curves of the device provided by the supplier and the transient results calculated by transient analyzing program CA-TIA2 and extracting the related data.The unknown transfer functions were finally gained using the parameter estimation models built in MATLAB software after getting the basic data.The identification results meet the requirements on the general design and performance verification of the control system.
