Abstract:
T wo methods of ant ibacklash are proposed for a class of servo systems w ith backlash affect ing t racking precision. Mult-i motor method, w hich includes ant ibacklash and negat ive feedback based on the dif ference of velocity of two motors , is desig ned for large radar antenna servo systems. It w as successfully used for some antenna system, and the performance of the system was improved greatly. For single-motor servo system, intelligent PID and rulebased compensat ion st rategy are presented. Pract ical applicat ion shows that it can improve pos-i t ion precision and tracking precision w ith ef fect.
