“…In order to evaluate the performance of a control algorithm, we introduce a quadratic loss (100, 100, 1, 1, 1), (1, 1). The values of the matrices has been taken with respect to some preliminary simulations and the well known interpretation of the penalization which states that the true values are kept on the desired ones with precision given by Q −1 t using zero control with precision R −1 t , [6].…”
