| Abstract: | The nose wheel steering servo system was introduced. It is mainly composed of electromechanism actuator, controller and displacement sensor. The electromechanical actuator adopts the screw-slider-fork design to realize the requirement of miniaturization and high load. The controller adopts dual-redundancy 422 bus design to ensure the reliability of communication. The poison closed-loop operation and real-time monitoring of the angle were achieved by dual-position-feedback. Through the ground test and flight test, it verify the system can meet the requirement of the indicators. |
