Abstract :
Communication scheduling is a crucial cause of interfering networked control stability. For data communication network triggered by event, time delay and packet dropout induced by scheduling policy is analyzed; quadratic performance criterion is computed under various timing conditions based on Continuous linear-quadratic-Gaussian theory; data packet is dropped voluntarily in collision of sending nodes is presented, implementing vary sampling period and priority reassignment scheduling policies. The simulation on Controller Area Network (CAN) validates the effectiveness of the proposed hybrid scheduling method.
