Dynamic matrix controller based on sliding mode control

This work presents a system of tuning equations, based on the sliding surface response, to predict the changes in the parameters of the process, which were used to improve and to tune the predictive dynamic matrix controller parameters. The controller presents a fixed structure and its tuning parameter equations were developed relating the characteristics of the sliding surface and the characteristic parameters of the first order plus deadtime model. Simulations on a blended tank with variable level that presents non linear behavior were considered.
