The utilization of the results of control theory in the process control field has been lagginig behind other application fields such as aerospace for many years. It is argued that the availability of high capacity computing at low price will change t

A model based control strategy for nonlinear multivariable processes having hard constraints on both control and state variables, is derived based upon the concept of Elementary Nonlinear Decoupling (END). In END a property space is defined which has
