Abstract:
By deriving an explicit expression for the observability Gramian G, it shown that the adjoint gradient is the image under G of the initial error in control. By relating the structure of the Gramian to the forward sensitivities of the model and the sensitivity of the forward operator, sufficient conditions - in terms of the number and placement of observations, for the positive definiteness of the Gramian G are derived.
