中文摘要
      针对带有空间变化的反应项的耦合分数阶反应--扩散系统边界镇定问题, 利用反步法设计了用于 Robin 边界条件的状态反馈控制. 通过可逆的积分变换将原耦合系统转化为一个稳定的目标系统. 利用变量代换和逐次逼近法分析了核函数矩阵的存在唯一性. 借助分数阶 Lyapunov 直接法证明了闭环系统的 Mittag-Leffler 稳定性. 数值仿真验证了所提出方法的有效性.
英文摘要
      The problem of boundary stabilization is considered for a class of coupled fractional reaction--diffusion systems with spatially varying reactions, and a state feedback control for Robin boundary conditions is designed by the backstepping method. The original coupled system is transformed into a stable target system through a reversible integral transformation. The existence and uniqueness of the kernel function matrix is analyzed by using variable substitution and the method of successive approximations. The Mittag-Leffer stability of the close-loop system is proved by the the fractional Lyapunov direct method. Numerical simulations verify the effectiveness of the proposed method.
