| Abstract: | Message model in the worst-case for CAN bus is analyzed and a schedule algorithm based on fixed priority is proposed. According to the requirement and characteristic of the real control system, messages which are transferred in the six degree of freedom system are scheduled with the fixed priority algorithm. Through experiments, it is proved that the algorithm improves the performance of the six degree of freedom system and the networks utilization. It is also proved that the messages deadline is satisfied. |
| Keywords: | CAN bus Fixed priority schedule algorithm(FPA) Six degree of freedom platform |
