Robust Stability of Model Predictive Control

Abstract

Model Predictive Control (MPC) has drawn attention as a powerful digital computer control method and has been successfully applied to many industrial processes. One of the reasons why MPC has been well received in industrial circles is its excellent robustness. An analysis of robust stability of this control system is attemtped in a comprehensive manner without performing numerical computation. It is confirmed that MPC guarantees stable, offset-free control for any stable process if a model possessing a non-decreasing step response is employed. © 1988, The Society of Chemical Engineers, Japan.
