A vibrating plate is here taken to satisfy the model equation:utt + Δ2u = 0 (whereΔ2u:= Δ(Δu); Δ = Laplacian) with boundary conditions of the form:uv = 0 and(Δu)v = ϕ = control. Thus, the state is the pair [u, ut] and controllability means existence ofϕ on Σ:= (0,T∂Ω transfering ‘any’[u, ut]0 to ‘any’[u, ut]T. The formulation is given by eigenfunction expansion and duality. The substantive results apply to a rectangular plate. For largeT one has such controllability with∥ϕ∥ = O(T−1/2). More surprising is that (based on a harmonic analysis estimate [11]) one has controllability for arbitrarily short times (in contrast to the wave equation:utt = Δu) with log∥ϕ∥ = O(T−1) asT→0. Some related results on minimum time control are also included.

This research was partially supported under the grant AFOSR-82-0271.
