Airborne Antenna Tracking System Design And Engineering Implementation

In order to develop the airborne antenna tracking system, the most attention is paid to the design and implementation of the airborne antenna tracking system, which is based on the Global Position System, electronic compass and tilt sensor component. And the implementation of the controller is based on dual microprocessors, and the characteristic of the controller includes small cubage, light weight, high integration and broad operation temperature. The reliability, stability and the accuracy of the system are verified with the test of the low temperature and the vibration. And the expected performance index of the system is achieved. At the same time, the backlash is studied. In order to reduce the influence of backlash to the system, the control strategy of intelligent PID, compensation control and feedback of angle difference are introduced. The results of computer simulation prove that the above methods are feasible.
