摘要
涉及两个离散延迟的微分方程有助于在一个模型中模拟两个不同的过程。我们对 ab 平面上的分数阶延迟微分方程 Dαx(t)=ax(t)+bx(t-τ)-bx(t-2τ) 进行了稳定性和分岔分析。稳定区域包括稳定、不稳定、单一稳定区域(SSR)和稳定开关(SS)。在稳定区域,系统在所有延迟值下都是稳定的。SSR 区域有一个临界延迟值,它使稳定和不稳定行为分叉。在 SS 区域可以观察到稳定和不稳定行为的切换。
Analysis of a class of two-delay fractional differential equation.
The differential equations involving two discrete delays are helpful in modeling two different processes in one model. We provide the stability and bifurcation analysis in the fractional order delay differential equation Dαx(t)=ax(t)+bx(t-τ)-bx(t-2τ) in the ab-plane. Various regions of stability include stable, unstable, single stable region (SSR), and stability switch (SS). In the stable region, the system is stable for all the delay values. The region SSR has a critical value of delay that bifurcates the stable and unstable behavior. Switching of stable and unstable behaviors is observed in the SS region.
