摘要
讨论了区间离散广义系统的静态输出反馈鲁棒H∞控制问题,在给出区间离散广义系统的等价描述之后,基于系统参数矩阵不等式,得到了问题可解的充分条件,并给出了输出反馈控制器显式表示,所得控制器保证闭环系统是容许的,且满足给定的H∞性能指标,数值例子说明了该方法的可行性。
The problem of static output feedback robust H∞ control for a class of interval discrete-time singular systems is discussed. Firstly, a kind of equivalent description of the interval discrete-time singular systems is given. Then a sufficient condition for solvability of the problem and the explicit expression of static output feedback robust H∞ controller are obtained in terms of matrix inequalities. The designed controller guaranteed that the closed-loop systems is regular, causal, stable and satisfying a prescribed H∞ norm bounded constraint. Finally, a numerical example is given to demonstrate the feasibility of the proposed method.
