Abstract: This paper presents two alternative control methods for plants modelled by a deterministic I/O automaton: A feedforward and state-feedback controller. The control aim is to steer the plant into a desired final state, which is given during operation and is not known in advance. For the definition of the controller a new trajectory matrix is introduced, which for each pair of plant states represents the first state transition corresponding to the shortest path connecting the states. The feedforward controller is modelled by a deterministic I/O automaton as a sequential logic. The state-feedback structure simplifies the representation of the controller to an I/O map. It is proved that both controllers steer the plant on a shortest state trajectory into the desired final state. The results are demonstrated by an experimental application on a handling system.
