- 基于线性矩阵不等式（LMI）方法,研究了线性不确定离散时滞系统的鲁棒非脆弱H∞ 状态反馈控制器的设计问题.系统的不确定项参数和控制器的增益变化都是时变的且满足线性分式形式的范数有界.考虑了控制器增益存在加性和乘性摄动的2种情形,以LMI形式给出了非脆弱H∞控制器存在的充分条件,保证了闭环系统的鲁棒稳定性和一定的H∞衰减水平.实例表明了该设计方法的有效性.
- Abstract:
- This paper deals with the problem of robust and nonfragile H∞ control via s tate feedback for linear discretetime systems with timedelay and normbound ed parametric uncertainties by using a method of linear matrix inequality (LMI). Both the gain perturbations of the controller and the uncertain terms of the sy stem are timevarying and normbounded with linear fractional form. Moreover, the gain perturbations of the controller are considered to be either additive or multiplicative. Sufficient conditions for the existence of a robust and nonfr agile controller are given in terms of LMI, so the resulting closedloop system is robustly stable and attains a certain H∞ attenuation level. A numerical e xample is provided to demonstrate the effectiveness of the method.
