Abstract:

An objective and accurate assessment of the overall operation situation of the control system can help the controller to control the operation state of the control system on the macro level. To solve the problem, an operation situation assessment method of control system based on the interdependent network and support vector machine(SVM) is proposed. The control-aircraft state interdependent network model is used to represent the control system, which fully considers the overall state of aircrafts and controllers. The interdependent network indicators are used to describe network operation situation. Choosing SVM as assessment method, the operation situation assessment problem is transformed into a classification problem. The distance from the point to the smooth operation classification boundary is used as an index to assess the operation situation of the control system, thus reducing the influence of subjective factors on the assessment method. The results of simulation analysis and an example analysis at Changshui Airport show that the assessment method can give specific operation situation values of the control system and provide objective and accurate situation information for the controllers.

Key words: air traffic control, complex network, interdependent network, support vector machine (SVM), situation assessment
