Timoshenko梁的边界最优控制

Abstract

Abstract: This paper studies the boundary optimal control problem governed by a Timoshenko beam equation. Firstly, the well posedness of the system is token by using the theory of the linear operator semigroup. Based on the objective function, the optimality principle (the maximum principle) and the corresponding optimal control are obtained by using the adjoint system. Finally, by the eigenfunction asymptotic expansion of the homogeneous system, the exhaustive calculation steps of optimal control and optimal trajectory are given.

Key words: Timoshenko beam, Boundary optimal control, Adjoint system, Maximum principle
