Is suboptimal nonlinear MPC inherently robust?
We study the inherent robust stability properties of nonlinear discrete-time systems controlled by suboptimal model predictive control (MPC). The unique requirement to suboptimal MPC is that it does not increase the cost function with respect to a well-defined warm start, and it is therefore implementable in general nonconvex problems for which no suboptimality margins can be enforced. Because ...
متن کاملA Reduced Dantzig-Wolfe Decomposition for a Suboptimal Linear MPC
Linear Model Predictive Control (MPC) is an efficient control technique that repeatedly solves online constrained linear programs. In this work we propose an economic linear MPC strategy for operation of energy systems consisting of multiple and independent power units. These systems cooperate to meet the supply of power demand by minimizing production costs. The control problem can be formulat...
متن کاملOn the inherent robustness of optimal and suboptimal MPC
The stability of nominal model predictive control (MPC) is well characterized in the literature. Lyapunov theory forms a framework that unites both linear and nonlinear control problems, and it is amenable to a wide variety of new MPC formulations (see (Rawlings and Mayne, 2009, Ch. 2) and the references it contains). In all practical implementations, however, robustness to disturbances is a re...
متن کاملSuboptimal MPC and partial enumeration: robust stability and computational performance
We revise in this paper the Partial Enumeration (PE) method for the fast computation of a suboptimal solution to linear MPC problems. We derive novel robust exponential stability results for difference inclusions to show that the existence of a continuous Lyapunov function implies Strong Robust Exponential Stability (SRES), i.e. for any sufficiently small perturbation. Given the fact that the s...
متن کاملConditions under which suboptimal nonlinear MPC is inherently robust
We address the inherent robustness properties of nonlinear systems controlled by suboptimal model predictive control (MPC), i.e., when a suboptimal solution of the (generally nonconvex) optimization problem, rather than an element of the optimal solution set, is used for the control. The suboptimal control law is then a set-valued map, and consequently, the closed-loop system is described by a ...
