Research on Two Kinds of Parameter Identification Methods for Short-Term Time-Varying System

Abstract:

In this paper, two kinds of time varying parameter identification methods which are called identification method of using broken line to approximate time varying parameter and identification algorithm with auto-regulation forgetting factor are studied. The two methods are used for short-term time-varying system parameter identification in simulations. According to the results of the simulations, the applicable conditions of the two kinds of identification methods are analyzed. The results of the simulations indicate the effectiveness of the two methods. Furthermore whether the two kinds of identification methods are sensitive to noise or not is studied by setting different noise levels in the simulations. Finally, experiments of a variable mass cylindrical shell are adopted to demonstrate the efficiency of the two kinds of time varying parameter identification methods.
