| Abstract: | To meet the needs of camera onboard mini Unmanned Reconnaissance Aerial Vehicle(URAV),a synchronous focus control circuit of camera lens controlled by stepper motor was designed.The driving of the bipolar stepper motor was implemented and the functions of rapid and smooth zooming and focusing during high speed flight were realized by adopting the redundant I/O resources of ARM processor inside the URAV control system and a SiTI company’s MD127 stepper motor driver IC.Flight tests showed that the system can work reliably and accurately. |
