针对一类结构不确定性线性采样系统 ,在时域中用 L yapunov方法研究采样系统的鲁棒控制及最优鲁棒控制 ,给出了系统鲁棒稳定的充分条件以及相应的鲁棒控制律。控制律的求取借助于求解一类线性矩阵不等式 (L MI) ,或求解满足特定线性不等式条件下的优化问题。算例结果表明 ,采样周期是一个关键性的设计参数。
For a class of linear sampling system with structural uncertainty, L yapunov method is used to study the robust control and the optimal robust control of the sampling system in the time domain. The sufficient conditions for the robust stability of the system and the corresponding robust control law . The control law is obtained by solving a class of linear matrix inequalities (LMI) or solving the optimization problem that satisfies a particular linear inequality. The results show that the sampling period is a key design parameter.
