Abstract
Model predictive control with disturbance attenuation requires solving on-line a constrained minimax problem, which is in general non-convex. In this talk, we relax the infinite horizon minimax problem using Lagrange duality. As shown, one can focus on the Lagrange (weak) dual problem instead of the primal one. For linear constrained systems, we formulate the problem to be on-line solved in the framework of LMI optimization, which is computationally tractable. We also discuss some issues of the resulting moving horizon closed-loop system, including feasibility, conservatism of the solution, dissipation, disturbance attenuation. Extensions to uncertain and nonlinear systems are also highlighted.
