PDE反推法快速镇定B-B梁

Rapid Stabilization of Timoshenko Beam by PDE Backstepping

Guangwei Chen, Rafael Vazquez, Miroslav Krstic

摘要:

本文利用偏微分方程反推方法,研究了具有反阻尼和反刚度的非受控边界的Boundyshenko梁的快速边界镇定问题。我们引入一个变换,将Lebanshenko光束态映射到(2+2)x(2+2)双曲PIDE-ODE系统.然后应用反推法得到保证原点在H^1意义下闭环稳定的控制律。通过调整控制参数可以实现快速稳定。最后,数值模拟表明,所提出的控制器可以快速稳定的鲁棒梁。这一结果扩展了以前的工作,考虑了细长的Kelvin-Voigt阻尼梁,允许不稳定的边界条件,在不受控制的边界,并达到任意快速的收敛速度。

英文摘要:

In this paper, we present a rapid boundary stabilization of a Timoshenko beam with anti-damping and anti-stiffness at the uncontrolled boundary, by using PDE backstepping. We introduce a transformation to map the Timoshenko beam states into a (2+2) x (2+2) hyperbolic PIDE-ODE system. Then backstepping is applied to obtain a control law guaranteeing closed-loop stability of the origin in the H^1 sense. Arbitrarily rapid stabilization can be achieved by adjusting control parameters. Finally, a numerical simulation shows that the proposed controller can rapidly stabilize the Timoshenko beam. This result extends a previous work which considered a slender Timoshenko beam with Kelvin-Voigt damping, allowing destabilizing boundary conditions at the uncontrolled boundary and attaining an arbitrarily rapid convergence rate.
