Abstract: For the high-precision tracking performance of machine tool motion axis control, this paper establishes a system mathematical model considering the elastic deformation of ball screws, and then designs a sliding mode controller to suppress the influence of uncertainty on control performance. Next, an extended state observer was designed to observe the system state and disturbances, and feed them back to the sliding mode controller for position control. Finally, the correctness of the designed sliding mode control and extended state observer was demonstrated through MATLAB simulation analysis.
