  • 摘要: 研究一类参数不确定的2D时滞系统满足Lipschitz条件的非线性Fornasini-Marchesini模型(简称2-DFMII)的鲁棒能稳问题,即设计静态状态反馈控制律,使得对所有容许的不确定参数,闭环系统稳定.通过求解线性矩阵不等式(LMI),给出了问题可解的充分条件及静态状态反馈控制律的设计方法.最后通过数值算例验证了方法的有效性.

     

    Abstract: This paper discusses the problem of robust stabilization for uncertain 2D discrete state-delayed systems in the Fornasini-Marchesini second local state-space model with a class of generalized Lipschitz nonlinearities. The parameter uncertainty is assumed to be norm-bounded. The purpose of the problem to be addressed is to design state feedback controllers such that the resulting closed-loop system is stable for all admissible uncertainties. In terms of a linear matrix inequality (LMI), a sufficient condition for the solvability of the robust stabilization problem is obtained, and a desired state feedback controller can be constructed by solving a certain LMI. A numerical example is provided to demonstrate the effectiveness of the proposed approach.
