中文摘要	The paper proposed a digital preview control scheme with a discrete time disturbance observer for linear motor, which is the key to NC turning for work-pieces with noncircular profile, and has the characteristics of a known target trajectory and sensitivity to external perturbation and parameter variety. Firstly, the position tracking errors of the linear motor servo system are reduced, through adding a preview feedforward to optimal state feedback control. Secondly, a discrete time disturbance observer is presented, regarding the external perturbation and parameter variety as the equivalent input disturbance, and the robustness of digital preview servo system is improved. The simulation results show that the control scheme can meet the requirements for turning work-pieces with noncircular profile in condition of high speed and high accuracy.
