研究一类不确定性的多时滞系统基于观测器的鲁棒 H∞ 控制问题 .系统的不确定性参数是时变的 ,但其结构已知 .通过构造观测器 ,并利用观测器状态进行反馈控制 ,使系统不仅鲁棒镇定 ,且具有一定的 H∞ 性能 .鲁棒 H∞ 控制器的设计可通过求解两个线性矩阵不等式得到 The robust H∞ control problem for a class of uncertain time-delay systems based on observer is studied. The uncertainty parameters of the system are time-varying, but its structure is known. By constructing the observer and using the observer state feedback Control, so that the system not only robustly stabilizes but also has some H∞ performance.The design of robust H∞controller can be obtained by solving two linear matrix inequalities
