Airborne Pod Control System Development On ARM

With the continuous development of embedded technology, Embedded systemgradually from the industrial control field to enter now living in all kinds of homeappliance equipment, The scope and application field is more and more widely, and now,The embedded technology has become an indispensable part of our life, it will bringmore convenience to us.The airborne pod because of its operating environment more complex, ofteninfluenced by aircraft vibration, wind resistance and other external conditions, thecontrol system requirements more stringent.In this paper, airborne pods ARM-based control system has been studied anddeveloped., Control system is divided into three modules, namely ARM hardwareplatform structures, software system migration and driver module development. Thehardware platform with the ARM series S3C2440A chip as core processor of thehardware system, The working principle and the using method of the hardwareplatform of memory and some peripheral were studied. By adding these peripheralhardware configuration of hardware platform, the hardware platform can be customizedaccording to the needs. Software systems including U-Boot boot system, Linuxoperating system and the root file system，Of these software systems analysis andresearch, modify the code in this article to support the hardware platform, throughdebugging, it successfully transplanted on ARM hardware platform. Driver moduledevelopment including hardware driver modules, drivers and feedback circuits. Firstcombined control requirements gondola study driven programming in the Linux system,Servo control system for modeling and studying classical PID control algorithm，InMatlab software under simulink environment control system simulation, write PIDcontrol procedures, driven programming under Linux system and add pod drive PIDcontrol algorithm program, the hardware and software parts of the above-describeddrive module.Finally, the integration of each of these modules, debugging the whole control system, through trial and error optimum control parameters through the final test results,the smooth operation of the nacelle, the control accuracy can be satisfied. The controlsystem has hardware and software customization easy, fast and efficient developmentsystem running stable.
