Research on online identification of T-S fuzzy model for hydraulic servo system with pump controlled cylinder
摘要
Abstract
The T-S fuzzy model of hydraulic servo system with the direct drive pump was established,the modal was conducted and analyzed as well,for the nonlinear uncertain and time-varying characteristics of the hydraulic system.Firstly,based on the improved fuzzy clustering scheme,the optimal selection method of clustering number c was given,and the hydraulic system model was built.Secondly,the recursive least squares method with forgetting factor was used to identify the parameters of system model,and the T-S fuzzy model of hydraulic servo system was obtained.And then no disturbance velocity compensation of the servo cylinder was realized,and the load stiffness perturbation was reduced.Finally,simulation experiments were given to show the better approximation accuracy and generalization ability of the proposed scheme.关键词
