    Abstract

    In order to make up for low precision of the current position tracking system and inconvenience of the data cable transmission, a kind of high precision and wireless angular position tracking control system is designed. Multirange and higher accuracy L3G4200DH triaxial gyro as angular position sensor is adopted, the data transmission by 2.4 G NRF24L01 wireless radio frequency transceiver chip is realized, ARM Cortex -M3 as micro controller is used, and servo motor is controlled by fuzzy PID full closed loop control algorithm. Moreover, add advanced correction and feed-forward links to improve response lag of angle input. Consequently, decrease the error of the system. At the same time, the wireless video module is used to monitor servo motor state in real time. The simulation and experimental results prove that the servo system has been improved greatly in accuracy and real time, and the dynamic following error can be up to 10-3. Furthermore, the system has good following characteristic, meanwhile, wireless data transmission mode will give remote control and special working environment to bring a great convenience.
