Abstract

In order to be able to comprehensively consider both network communication control performance and network communication in the network control system, and to balance the network resources, improve the network performance, this paper proposes a new information distribution of CAN data identifier , and adopts a improved fuzzy maximum priority scheduling strategy. This paper proposes a design of information distribution in the communication message identifier domain for CAN bus, and adopts a modified fuzzy maximum priority scheduling strategy based on feedback to calculate the message priority of communicating message. Identifier domain information is distributed into message ID and node number. Message ID is updated by scheduling calculation, and the node number is set initially remaining unchanged. This can ensure the CAN data identifier domains do not conflict. The fuzzy priority scheduling strategy takes loop control error, error change and network latency as the input of fuzzy control algorithm and it dynamically updates priority of each loop in the network control system.
