Offset-Free Strategy by Double-Layered Linear Model Predictive Control

Abstract EN

In the real applications, the model predictive control (MPC) technology is separated into two layers, that is, a layer of conventional dynamic controller, based on which is an added layer of steady-state target calculation.

In the literature, conditions for offset-free linear model predictive control are given for combined estimator (for both the artificial disturbance and system state), steady-state target calculation, and dynamic controller.

Usually, the offset-free property of the double-layered MPC is obtained under the assumption that the system is asymptotically stable.

This paper considers the dynamic stability property of the double-layered MPC.
