摘　　要：利用Lyapunov方法研究带有非线性不确定参数的线性时滞系统的鲁棒稳定性和鲁棒镇定问题.针对该系统给出其鲁棒稳定性条件及无记忆状态反馈控制器设计方案,所得判别条件和控制器均以LMI的形式给出.最后给出算例说明结论的有效性.It is studied that the problem of robust stability and robust stabilizing for linear time - delay systems with nonlinear uncertain parameters by making use of Lyapunov method. Presented here are the condition of robust stability and the design method of memoryless state feedback controller for the system; the criterion condition and the controller are given in the form of linear matrix inequality (LMI). An example is provided to illustrate the effectiveness of the results.
