| 摘 要： | 针对一类范数有界非线性不确定状态时滞系统，讨论其时滞依赖干扰抑制问题，得出了相应的LMI判据，通过设计的时滞依赖有记忆状态反馈控制律，可保证闭环系统的鲁棒稳定性且能优化二次型干扰抑制水平，当时滞较小时，具有较小的保守性，计算机仿真算例表明了该方法的有效性．

| Abstract: | The problem of delay dependent robust disturbance attenuation ior a crass of state-delayed systems with norm-bounded nonlinear uncertainties is discussed and the corresponding LMI criterion is obtained. The delay dependent memory state-feedback control law derived in terms of linear matrix inequality guarantees the robust stability of closed-loop systems and optimizes the disturbance attenuation level. Simulation example shows the effectiveness of the approach. |
