Abstract：This paper presents a novel distributed economic model predictive control(EMPC)strategy with stability guarantees for state-coupled constrained nonlinear systems with communication delays.The optimal economic equilibrium point of the system is computed discretely,and a stabilizing optimal control problem related to this point is constructed.The optimal value function of the stabilizing control problem is then used to formulate implicit contractive constraints for the original distributed EMPC optimization.By employing terminal constraints and the input-to-state stability(ISS)lemma,the recursive feasibility of the distributed EMPC and the ISS property of the closed-loop system with respect to state deviations from the optimal economic equilibrium point are established.Finally,the effectiveness of the approach is demonstrated using a cascade of nonlinear continuous stirred tank reactors.
