一种用于无人机的分布式飞行控制系统设计①

分布式结构已广泛应用于高可靠航空电子设备的设计中。设计了一种基于控制局域网（CAN）的分布式飞行控制计算机,用于在执行飞行任务过程中无人机的飞行控制律解算和系统管理。根据无人机控制的实时性和可靠性需求,提出了一种CAN通信、双端口随机访问存储器（DPRAM）通信和控制任务相互配合的内部通信机制。实验表明根据该通信机制设计的通信方案完全满足无人机控制的实时性和可靠性要求,同时解决了分布式结构引入的数据延时问题。

Design of a Distributed Flight Control Computer for UAV

Distributed architecture has been widely used in the design of reliable avionics. Distributed flight control computer designed based on Controller Area Network (CAN) is used for flight control law solution and system management of unmanned aerial vehicle (UAV). According to real-time UAV control and reliability needs, an inner communication mechanism of distributed flight control computer which integrates CAN communication, dual-port random access memory (DPRAM) communication and control tasks is put forward. Experimental results show that the communication mode designed according to the communication mechanism meets the real-time UAV control and reliability requirements, and solves the problem of the data delay caused by distributed architecture.
