Aiming at the model of rudder angle in wind tunnel tests need to repeat change, an electric actuator system based on CAN bus for model in wind tunnel test was proposed. Introduced the structure and the working principle of electric actuator, the model rudderand and the elevator motor actuator was developed. Then conventional load test and repeat test of wind tunnel were conducted with the D600 model. Results show that the system can realize the auto-control of the control plane in wind tunnel test, the precision of the test can meet all of the qualified indicators and part excellent indicators of the GJB. In a word, this digital servo system has good reliability, good accuracy and high control precision.
