摘　　要： 为了满足无人机飞行控制系统向高精度和小型化方向发展的需要,以高性能的32位微处理器MCF5235为核心,搭建了高性能的数字式无人机飞行控制系统;并根据无人机飞行控制系统的控制原理和控制策略,进行了飞行控制软件的功能模块和任务划分,着重分析了嵌入式Linux实时操作系统下主函数的任务调度机制。MCF5235以它的高集成度、低功耗和强大的处理能力提高了系统的可靠性,减少了系统的体积;尤其是嵌入式Linux的使用,进一步提高了系统的可靠性,增强了系统的实时性。 In order to follow the development trend of high precision and miniaturized flight control system for UAV, a digital flight control system with high performance is built, which is based on M CF5235 micro-processor. At the same time, based on the control theory and control policy of flight control system, software function module and tasks division are designed, especially the task schedule law of main function is analyzed. System reliability is increased and capacity is reduced because of its high integrated level, low power and powerful processing capacity of MCF5235 ,especially using embedded Linux, the reliability of system is further improved and real time of system is strengthened.
