In order to research the dynamic characteristics of the ball screw on the Fiveaxis linkage machining center, such as positioning accuracy, repeated positioning accuracy, speed and acceleration tracking, dynamic friction torque, load disturbance, preload, fatigue performance, temperature rise and mechanical vibration, an intelligent precision measurement and control test platform is designed, which includes servo motor + ball screw driving, linear motor simulation load disturbance and multichannel signal acquisition. And the dynamic model of timevarying parameter uncertainty and external force disturbance is described. Meanwhile, the adaptive nonlinear PID control model and feedforward error compensation based on genetic algorithm are established. The test result shows that the control strategy has a small tracking error, strong antijamming capability and stability.
