Decision-making Method for Control of A-SMGCS Taxiway Centre Line Lights

For automatic decision-making on the control command of A-SMGCS (Advance Surface Movement Guidance and Control System) taxiway centre line lights in line segment, Petri net based approach is proposed. Firstly, the dynamic operation model for taxiway line segment is established based on Petri net, and the corresponding marking control regulation is defined. And then, the controller synthesis for the operation model is fulfilled based on the local incidence matrix approach and it can prevent the model from evolving into forbidden states. Furthermore, the control command decision-making method and corresponding algorithm are provided based on the state of transition. Finally, an example on the decisionmaking of control command for taxiway centre line lights demonstrates the effectiveness of this approach.
