Finite time stability practically examines the trajectories of a system which converge to equilibrium state in a short period of time. This notion requires predefined bounds on system parameters and bounded time interval. Considering the idea that many practical system often operates over time interval being finite rather than infinite, we explore the finite time stability concept of damped fractional system with neutral conditions and impulsive effects. The desired bounds for the stability of the system is derived by implementing Gronwall's inequality conditions. Further, the finite time stability conditions of the proposed fractional linear model is extended to nonlinearity term with disturbance. Finally, numerical simulations are given to show the effectiveness of the derived results.
有限时间稳定性实际研究的是在短时间内收敛到平衡状态的系统轨迹。这一概念要求对系统参数有预定义的界限以及有界的时间间隔。考虑到许多实际系统通常在有限而非无限的时间间隔上运行这一观点,我们探索具有中立条件和脉冲效应的阻尼分数阶系统的有限时间稳定性概念。通过应用格朗沃尔不等式条件得出系统稳定性的期望界限。此外,将所提出的分数阶线性模型的有限时间稳定性条件扩展到具有扰动的非线性项。最后,给出数值模拟以展示所得结果的有效性。
