Delay-dependent robust stabilization of a class of nonlinear uncertain neutral systems with multiple time delays
【摘要】 对一类具有多时滞非线性不确定项的中立型系统的鲁棒反馈控制问题,构造了Lyapunov泛函,给出了通过带记忆的反馈控制律,使闭环系统一致渐近稳定的分别与滞后量大小无关和相关的充分条件.
【Abstract】 The stabilization of a class of nonlinear neutral systems with multiple time-delays is considered. To stabilize the described system, a state feedback control law via compound memory and memoryless feedback is derived and, by the analysis method for constructing Lyapunov functional, delay-independent stability criteria are proposed, which are sufficient to ensure a uniform asymptotic stability property. Finally, two concise examples are provided to illustrate the feasibility of our results.
