【摘要】 提出了一种运动控制策略,通过滑模控制,转矩波动和摩擦补偿技术来获得滚珠螺杆驱动中高带宽高精度跟踪性能.利用该控制策略,在轴进给率为1000mm/s,加速度为9.80665m/s2的状态下,可以获得0.95μm的实验跟踪精度.更多还原

【Abstract】 This paper presents a motion control strategy that utilizes a combination of vibration avoidance,sliding mode control,and torque ripple and friction compensation techniques to facilitate high bandwidth-high accuracy tracking in ball screw drives.With the proposed control strategy,an experimental tracking accuracy of 0.95 μm has been achieved while traversing the axis at a feedrate of 1 000 mm/s with 9.806 65 m/s2 acceleration.更多还原
