| Since micro air vehicle plays an important role and has huge application prospect in military andcivil use, the hardware and sofrware development platform design of micro air vehicle flight controlsystem based on ARM-Linux was researched in this paper.Firstly, according to the analysis of typical mirco air vehicle flight control system both at homeand abroad, and based on the experience of project team and the requirements for micro air vehicleflight control system, the overall design scheme of mirco air vehicle flight control system based onARM processor was presented in this paper, including the design of airborne hardware platform andlow-level software development platform.Secondly, according to the analysis of memory space distribution, working stability anddebugging performance of flight control system, the core processor module of micro air vehicle flightcontrol system was designed. According to the analysis of power supply of flight control system, thepower supply module and voltage switching circuit design were studied. According to thecharacteristics of interface communication of sensors, executive parts and radio communicationmodule, certain interface circuits were designed in this paper.Thirdly, the software development platform of micro air vehicle flight control system based onembedded Linux was designed in this paper, including the transplating of embedded Linux and designof device driver. In order to enhance real time capability of flight control system, RTlinux kernelpatch was used to constitute two kernels Linux operation system, which can make real time responseup to microsecond level.Finally, the test and experiment of hardware and software platform of micro air vehicle flightcontrol system were studied, which verified the validity and feasibility of the whole system. |
