The function and the composition of the measurement system are analyzed. Aiming at one major-part butt item, the aided assembly process, the measurement data treatment and the measurement environmental layout are expatiated. Through the study, our technical base is expanded for the engineering application of the digital measurement technology in the aircraft assembly.
A digital servo controller based on CAN bus is introduced.Three pivotal techniques of the servo, including the hardware design, the motor control arithmetic and the software design are mainly studied, the hardware design is described particularly. The results show the correctness and effectiveness of the digital servo controller.
