Nonlinear system identification employing automatic differentiation [PDF]

open access: yesCommunications in Nonlinear Science and Numerical Simulation, 2013
An optimization based state and parameter estimation method is presented where the required Jacobian matrix of the cost function is computed via automatic differentiation. Automatic differentiation evaluates the programming code of the cost function and provides exact values of the derivatives.
