Nonlinear predictive control for setpoint families

Varying product specifications and load changes require that operating points have to be changed frequently during the operation of many processes. Hence controllers have to guarantee stability for all setpoints and allow smooth transfer between setpoints. We propose to combine pseudolinearization and quasi-infinite horizon nonlinear predictive control for the solution of this problem. The pseudolinearization is used to obtain a closed expression for the controller parameters as a function of the setpoints, such that for every setpoint stability of the closed loop is guaranteed
