两自由度控制器的直接数据驱动辨识
Direct Data-driven Identification for Controllers with Two Degrees of Freedom
摘要
Abstract
In closed loop structure, the problems of direct data driven identification about nonlinear controller and linear controller are studied when one nonlinear plant exists. Without identifying the nonlinear plant, the problem of designing the nonlinear controller is changed to the nonlinear system identification under one basis function expansion. For devising the closed loop linear conroller, this paper introduces the virtual feedback tun-ing idea to identify the parameters of linear controller by using recursive least squares method. In closed loop structure, one Lipschitz continuous assumption of the nonliear system is added and one finite gain stability no-tion is defined. Then some inequalities about Lipschitz constants are derived to guarantee that the nonliear sys-tem's output is finite gain stable. Finally, it verifies the efficiency of the proposed strategy by the simulation ex-ample results.关键词
