“…Let us be given a positive constant λ > 0, a continuous Lipschitz function χ ∈ W 1,∞ (Ω, R) with nonempty support, and a solutionû ∈ W st of (1) with ζ = 0, in a suitable Banach space W st . Then, following the procedure presented in [BRS11], we can prove that there exists an integer M = M (|û| W st ), a function η = η(t, x), defined for t > 0, x ∈ Ω, such that the solution u = u(t, x) of problem (1), with ζ = χP M η, and supplemented with the initial condition That is, the internal control ζ = χP M η stabilizes exponentially, with rate λ, the Burgers system to the reference trajectoryû.…”
