摘　　要：基于Roesser模型研究不确定非线性离散时滞2D系统的H∞控制保性能问题，在非线性项和不确定项满足特定的条件下，分别导出具有H∞控制性能的有记忆状态反馈保性能控制器存在的充分条件，寻找出H∞保性能控制器的优化设计方法，使得闭环系统在渐近稳定的同时，小于某个确定的上界。最后通过仿真验证有记忆状态反馈H∞。保性能控制器设计方法的有效性。This paper is researched on the problem of memory state feedback H∞ guaranteed cost control for uncertain nonlinear discrete time 2D systems with state delay based on Roesser model. Under nonlinear term and uncertainties satisfying the given condition, separately educe the sufficient condition of the existence of memory state feedback guaranteed cost controller with H∞ control performance, and find out the design optimization method of H~ guaranteed cost controller, so that the closed-loop system is asymptotically stable,in the meanwhile,less than a certain limit. Simulations indicate that design method of memory state feedback H∞ guaranteed cost controller is effective.
