摘要
根据先进无人飞行器对实时性和小型化的要求,介绍了某型无人飞行器飞行控制系统的总体设计和具体实现方案。本系统以TMS320F2812数字信号处理器为核心,外围扩展了高精度的AD/DA转换器、多串口通道和外部存储器,使系统具有较丰富的硬件资源。软件设计以直接设计方式开发,软件系统载于DSP FLASH中,并给出了相应的飞控软件流程图。整个系统性能优良,可扩展性强,成本低,适用于小型无人飞行器。
This paper introduces primarily the total design and the specific realization of a UAV＇ s platform to meet the requirements of real - time and miniaturization of aircraft. The system regards the digital signal processor of TMS320XF2812 as the kernel,including the high accurate AD/DA converter, UART interface and memory and making the system has abundant hardware resources. Software system is loaded into FLASH of DSP, which is developed by direct procedure design. The soft flow chart of filght control system is provided. The system has the good performance, powerful expandability and low cost, which make it more applicable to the MINI UAVS.
