摘要:

本文研究一类具有时变系数以及 Dirichlet 和 Robin 边界扰动的抛物型方程的输入到状态镇定问题。通过使用可降低控制设计与实现复杂度的时不变核函数,采用 backstepping 方法设计了一种基于观测器的输出反馈控制器。借助可用于处理 Dirichlet 边界项的广义 Lyapunov 方法,在空间 $L^\infty$ 范数下建立了输出反馈控制下闭环系统以及状态估计误差系统的输入到状态稳定性。数值仿真验证了理论结果,并说明了所提控制方案的有效性。

英文摘要:

This paper addresses the problem of input-to-state stabilization for a class of parabolic equations with time-varying coefficients, as well as Dirichlet and Robin boundary disturbances. By using time-invariant kernel functions, which can reduce the complexity in control design and implementation, an observer-based output feedback controller is designed via backstepping. By using the generalized Lyapunov method, which can be used to handle Dirichlet boundary terms, the input-to-state stability of the closed-loop system under output feedback control, as well as the state estimation error system, is established in the spatial $L^\infty$-norm. Numerical simulations are conducted to confirm the theoretical results and to illustrate the effectiveness of the proposed control scheme.
