Dynamic Matrix Control (DMC) is a concrete Model Predictive Control (MPC) algorithm. DMC controllers are characterized by means of a set of three parameters, i.e., prediction horizon p, control horizon m and implementation parameter lambda. In this paper authors provide further insight into the performance of DMC controllers when dealing with unstable systems carrying out a sensibility analysis with the lambda parameter, analyzing the value of four performance indexes devoted to measure the accuracy and the time issues of the response of the controlled unstable systems. To accomplish this study a total of 2,400 different experiments have been carried out.
