BASED ON CONFIDENCE INTERVAL ESTIMATION APPLICATION RESEARCH FOR IDENTIFIED DYNAMIC PARAMETER USING METHOD OF STABILIZATION DIAGRAM

摘要：

Identifying the order of system method of stabilization diagram is a novel approach,but it may yield false modes. The false mode can be effectively yielded because the model confidence factor is utilized. However,there are several similar mode in the corresponding order which is identified further modal parameters. Then arbitrary value from further modal parameters will usually be the recognition result. This paper will be analysis for the distinguishing results through making use of confidence interval estimation in the parameter estimation methods. Therefore the true value of identified results is included in random interval which is belonged to the certain confidence level.
