CSME System EIV-RLS Identification Modeling Method and Its Accuracy Analysis
摘要
Abstract
Contactless synchronous motor excitation(CSME)system has diversiform compensation networks and topological circuits,so the modeling method requires a high degree of versatility and portability.In view of the problem that traditional modeling method relies heavily on clear topology circuit and specific working state,this paper proposes an estimate initial value recursive-least-squares(EIV-RLS)identification modeling method.After sampling and transforming the input and output data,judged system order by akaike information criterion(AIC).Then obtained system parameter estimation by EIV-RLS algorithm and established system small signal model.Through Matlab/Simulink respectively simulated least-squares(LS),zero initial values recursive-least-squares(ZIV-RLS)and EIV-RLS identification modeling for series-series(S-S)type CSME system.Compared and analyzed the accuracy of three methods and verified the generality of EIV-RLS identification modeling method.Finally,through the test of CSME system prototype,verifies the EIV-RLS identification modeling method is effectiveness and accuracy.关键词
