As the core component of aircraft anti-skid brake system, the wheel sensor is directly related to the property of the anti-skid brake system. In order to test the function and performance parameters of the wheel sensors, a general intelligent measuring system for the aircraft wheel sensor is designed. The measuring system is based on computer control, a digital PID servo control system based on speed and negative angular acceleration feed forward is developed. The realistic simulation of the speed and negative angular acceleration of the aircraft wheel sensor is realized. The results show that this system can test a variety of wheel sensors, and runs stably, reliably and intelligently. The detection efficiency and detection precision are up to the desired results.
