摘要

为了提高间接位置控制双电机齿轮齿条驱动装置的精度，我们提出了一种新方法，在测试台上使用两个电机的编码器。通过对这些电机进行电预载，两个传动系统不会同时出现反向间隙。小齿轮和齿条之间的持续接触，以及由此对工作台的力传递，都通过与反向间隙信号的切换而得到保证。因此，在控制回路中消除了反向间隙，在没有直接工作台位置感应的情况下提高了系统精度。实验表明，与间接控制相比，跟踪误差减少了 59%。

Dual motor position feedback control for electrically preloaded rack-and-pinion drive systems to increase accuracy

To increase the accuracy of indirect position-controlled dual motor rack-and-pinion drives, a new approach is being proposed that uses the encoders of both motors on a test bench. By electrically preloading these motors, backlash does not occur simultaneously in both drive trains. Continuous contact between the pinion and rack and thus force-transmission to the table is ensured, by switching away from the signal with backlash. Backlash is therefore eliminated from the control loop and the system accuracy without direct table position sensing can be increased. Experiments show that the tracking error is reduced by 59 % compared to indirect control.
