提出了一种CAN总线通信报文仲裁场标识符信息的分配方法,将标识符信息设计为报文ID和节点序号2部分,其中,节点序号固定为节点初始编号,避免网络标识符冲突,报文ID采取基于反馈的改进型模糊最大优先调度策略(N-FFS)动态更新.所设计的N-FFS综合考虑了回路控制误差、误差变化率和回路网络延时,实时计算网络控制回路优先级,确保网络控制系统整体性能均衡.仿真结果表明,N-FFS具有良好的调度能力,能够很好地改善系统整体性能.
A method for allocating information of arbitration field in CAN bus communication message is proposed. The identifier information is designed as part of message ID and node number 2, in which the node number is fixed as the initial node number to avoid collision of network identifiers and report The document ID is based on the feedback of the improved fuzzy maximum priority scheduling (N-FFS) dynamic update.The designed N-FFS integrated circuit control error, error rate of change and loop network delay, real-time calculation network control loop priority , To ensure that the network control system overall performance is balanced.The simulation results show that N-FFS has good scheduling ability, can improve the overall system performance.
