系統辨識中不同噪聲情況的研究
Different Noises in System Identification
-
摘要: 對實際過程中的量測噪聲和系統噪聲進行了分析,并做了仿真研究,仿真結果了解到它們的差別,這對利用系統辨識的方法來建模和參數估計是有益的,還提出一種交替矩陣方法,它不僅可用來進行參數估計還可用來求解病態矩陣問題。Abstract: The measurement noise and system noise in the practical process are studied. The analysis and the simulation results show that the impulse responses of them are different. It is profit for modelling aad system parameter estimation. The Rotation Matrix method is also proposed. It not only estimates system parameters but also finds the solution of ill-matrix.
