通过引入上拟单调概念,得到了新的比较原理,在此基础上,利用Lyapunov直接方法和Lyapunov比较方法,讨论分数阶微分系统的两度量稳定性,得到几个稳定性判据。
Fractional differential systems have great applications in many fields of fluid flow rheolo- gy, diffusive transport etc. Two measure stability are investigated by using Lyapunov direct method and Lyapunov comparison method. A new comparison theorem is established by introducing the notion of upper quasi-monotone. Meanwhile, some stability criteria are obtained.
