Abstract:
Discrete-event systems occur often in the manufacturing field, but due
to the characteristics of these systems Model Predictive Control (MPC)
is not frequently used for them. This paper approaches MPC of an
Automated Storage/Retrieval System (AS/RS) by using Mixed Logical
Dynamical (MLD) modelling. Propositional calculus is used to transform
the non-linear dynamic model equations and constraints of the AS/RS
into the MLD form. We consider a performance index that makes sure
that customer demand is satisfied as soon and as efficiently as
possible. The MLD model and performance index are reformulated as an
integer linear programming problem. A case study is performed on a
laboratory stacker crane, and the simulations results illustrate the
good performance of the control algorithm.
