摘要
研究了一类非线性时滞系统的有限时间稳定性,给出了一些新的时滞无关和时滞相关的有限时间稳定性结果。应用Razumikhin方法 (R方法),给出了一般非线性时滞系统的一个有限时间稳定性判据。为了研究这类系统的有限时间稳定性,根据正交分解法和坐标变换方法,得到了这类系统的一个等价形式。基于上述得到的稳定性判据和等价形式,给出了这类系统的几个时滞无关和时滞相关的稳定性结果。通过仿真模拟验证了该方法的有效性。
The finite-time stability (FTS) of a class of nonlinear time-delay systems was investigated, and some delay- independent and delay-dependent FTS results were obtained. A criterion on the FTS was proposed via the Razumikhin approach (R-approach), and an equivalent form was obtained for this class of systems by means of coordinate transfor- marion and orthogonal decomposition of vector fields. Based on the criterion and the equivalent form, some delay-independent and delay-dependent conditions on the finite-time stability were derived for the systems. An illustrative example showed the results obtained effectively worked in the FTS analvsis for the nonlinear time-delav svstems.
