Cruise control using model predictive control with constraints

Model Predictive Control (MPC) originated in process industry, but in recent years it has been used in many applications beyond this sector. MPC implies solving a quadratic optimisation problem with constraints online. For a practical prototype implementation, it is often necessary to implement the optimisation method yourself. First, the application is presented; then an overview of the most important optimisation methodologies is given. A modified Active Set Method (ASM) is derived. The advantage of this method is its straightforward implementation and good timing behaviour. This method is compared to a commercially implemented Interior Point Method (IPM) on a numerical example and on a real-life implementation. (C) 2008 Elsevier B.V. All rights reserved.
