不确定时滞组合系统的H_∞动态输出反馈控制

Dynamic H_∞ Output Feedback Control for Uncertain Time-delay Large-scale Systems

研究一类状态、时滞项及输出均带有不确定项的时滞关联大系统的H∞动态输出反馈控制器设计问题,使得闭环系统稳定,且满足H∞范数小于给定界γ.利用LMI方法给出该控制器存在的充分条件,不需要调整参数,最后给出的设计实例验证了所得结果的有效性.

The problem is addressed via H∞ dynamic output feedback for time-delay large-scale systems with norm-bounded parameter uncertainties based on a method of linear matrix inequality. The sufficient condition for the solutions to the problem is presented in terms of LMI. A numerical example is provided to demonstrate the validity of the proposed design approach.
