Review: The utopia-tracking （UT）strategy is efficient for multi-objective model predictive control(MOMPC) concerning economic criteria. However,the feasibility region of the UT strategy is relatively small due to the relatively tight terminal equation constriant, and also there is a lack of robust stability studies in this field. Based on the UT strategy, a new multi-objective economic model predictive control (MOEMPC) scheme with a new termianl constraint, which can deal with multiple changing economic criteria, was proposed in this paper. Robust stability of the proposed MOEMPC scheme under bounded uncertainties is guaranteed based on the Input-to-State Stability (ISS) theory. Finally, a simple CSTR case example shows that the proposed MOEMPC enlarges the feasibility region of UT-MPC.
