Abstract : "This article presents two novel robust contractive economic model predictive control (EMPC) algorithms
with guaranteed input-to-state stability for nonlinear disturbed systems. Specifically, the first one adopts the nonquadratic
economic objective function and implements the control sequence in block fashion, i.e., re-optimizing
after all N control laws being applied. The second one takes receding horizon optimization strategy and only apply
the first element in control sequence at each step. By appropriately chosen the contraction rate r in contractive
constraint, the closed-loop system under each control algorithm is proven to be input-to-state stable. In order to
illustrate the efficiency of proposed algorithms, a disturbed CSTR model is utilized."
