The Research and Design of Auto-leveling Control System for Vehicle-borne Radar Platform Based on AVR

The paper puts forward an auto-leveling control system for vehicle-borne radar platform with four legs based on ATMEL AVR microcontrollers. In particular, the microcontrollers ATmega8515 and ATmega162 are used. By introducing the theory of auto-leveling, the methods to design the hardware and software of the embedded control system are presented. The system adopts highly accurate two-axis tilt sensor and digital AC servo-system, optimizes auto-leveling strategy and the acceleration and deceleration algorithm of servo-motor. The hardware and software design of the system make use of the concept of anti-interference and modularization. The test proves that this auto-leveling control system improves the leveling-precision and the stability of the performance, shortens the leveling-time, and satisfies the maneuverability and operating requirements of the vehicle-borne platform in formidable nature conditions
