The micro-motion positioning stage structure driven by high frequency response and short stroke voice coil motor is adopted, and the flexible spring is designed to provide sufficient stiffness for the system, and the straightness error compensation system of inkjet printing scanning axis is established. The mathematical model of voice coil motor direct-drive micro-motion positioning stage is analyzed, and the servo control method of this kind of motor is studied, and a position closed-loop controller based on PD control is proposed, which enhance the anti-interference ability of the system. The test results show that this method can meet the requirements of the straightness accuracy of the scanning axis of inkjet printing and has strong robustness.
