The main drawback of hybrid MPC is the heavy computation burden of the associated on-line mixed-integer optimization. Explicit MPC solutions overcome such a problem by rewriting the control law in piecewise affine form, but are limited to relatively simple hybrid control problem setups. This paper presents an alternative approach for reducing the complexity of computations by suitably constraining the mode sequence over the prediction horizon, so that on-line optimization is solved more quickly. While tracking performance of the feedback loop may be affected because of the suboptimality of the approach, closed- loop stability is guaranteed. The effectiveness of the method is demonstrated by an example. date: 2007 date_type: published publication: Decision and Control publisher: IEEE place_of_pub: 12th-14th December 2007 pagerange: 5264-5269 event_title: 46th IEEE Conference on Decision and Control event_location: 12th-14th December 2007 event_dates: New Orleans, LA id_number: 10.1109/CDC.2007.4434293 refereed: TRUE isbn: 978-1-4244-1497-0 book_title: Decision and Control official_url: http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=4434293&isnumber=4434000 citation: Ingimundarson, Ari and Ocampo-Martinez, Carlos and Bemporad, Alberto Suboptimal model predictive control of hybrid systems based on mode-switching constraints.
