Local controllability and non-controllability for a 1D wave equation with bilinear control

Abstract: We consider a linear wave equation, on the interval (0, 1), with bilinear control and Neumann boundary conditions. We study the controllability of this nonlinear control system, locally around a constant reference trajectory. We prove that the following results hold generically.• For every T > 2, this system is locally controllable in H 3 × H 2 , in time T , with controls in L 2 ((0, T ), R). • For T = 2, this system is locally controllable up to codimension one in H 3 × H 2 , in time T , with controls in L 2 … Show more

“…Various approaches were used to tackle the question of multiplicative controllability of hyperbolic equations like (1). The homogeneous version of (1) (i.e, f = 0) has been considered in [3,8,19,21,30]. The case of semilinear wave equation has been studied in [20] for equilibriumlike states of the form (y d 1 , 0) using two controls, i.e.…”

“…In [18], Coron proved that a positive minimal time may be required for the local controllability of the 1D model. In [8], Beauchard studied the minimal time for the local controllability of 1D wave equations with bilinear controls. In this reference, the origin of the minimal time is the linearized system, whereas in the present article, the minimal time is related to the nonlinearity of the system.…”

“…The study of a toy model (Beauchard 2011) suggests that if local controllability holds in 2D (with a priori bounded L 2 -controls) then a positive minimal time is required, whatever is. The appropriate functional frame for such a result is an open problem.…”
