Abstract
In model predictive control (MPC), an optimization problem is solved every sampling
instant to determine an optimal control for a physical system. We aim to accelerate this
procedure for fast systems applications and address the challenge of implementing the resulting
MPC scheme on an embedded system with limited computing power. We present the sensitivity-
based multistep MPC, a strategy which considerably reduces the computing requirements in
terms of floating point operations (FLOP) compared to a standard MPC formulation, while
fulfilling closed-loop performance expectations. We illustrate by applying the method to a DC-
DC converter model and show how a designer can optimally trade-off closed-loop performance
considerations with computing requirements in order to fit the controller into a tightly constraint
embedded system.
