摘要
首先给出了线性离散时滞重复过程的2D(两维)Roesser模型,采用线性矩阵不等式方法导出了过程稳定并具有H∞扰动抑制度的一个充分条件.通过求一个线性矩阵不等式的可行解来构造系统的一个状态反馈H∞控制器.进一步,通过求解一个线性矩阵不等式凸优化问题得到该过程的最优状态反馈H∞控制器.
The discrete linear repetitive process with time-delay is described by a 2-D state-space Roesser model. A sufficient condition is derived for this process to be stable and to have an H-infinity disturbance attenuation via the linear matrix inequality(LMI) approach. A state feedback H-infinity controller is then developed by solving a certain LMI. Furthermore, the optimal state-feedback H-infinity controller is obtained by solving a convex optimization problem with LMI constraints.
