Nettet1. jan. 2012 · INTRODUCTION Model predictive control (MPC) is a control strategy in order to approximately solve an optimal control problem on an infinite time horizon. To … Nonlinear model predictive control, or NMPC, is a variant of model predictive control that is characterized by the use of nonlinear system models in the prediction. As in linear MPC, NMPC requires the iterative solution of optimal control problems on a finite prediction horizon. While these problems are convex in linear MPC, in nonlinear MPC they are not necessarily convex anymore. This poses challenges for both NMPC stability theory and numerical solution.
