Backlash Compensation for Rack and Pinion Feed Drives based on Acceleration Measurement of the MachineTable

在这项研究项目中，提出了一种补偿齿条和小齿轮进给传动生产机间隙的新方法。其目的是通过根据测量的机床滑板的加速度产生补偿信号来提高进给驱动器的定位精度和控制质量。状态变量的测量是使用经济实惠的MEMS加速度计实现的，这种加速度计广泛用于智能手机和其他手持设备。额外的传感器系统可以直接集成到驱动器中，这允许简单的技术实施。测得的加速度信号还可用于对干扰力的补偿，为进一步改善运行性能提供了可能。

In this proposed research project, a new method for compensating the backlash in production ma-chines with rack and pinion feed drives is developed. The objective is to improve the positioning accuracy and the control quality of the feed drive by generating a compensation signal based on the measured acceleration of the machine sled. The measurement of the state variable is realized using cost-efficient MEMS-accelerometers, as widely used in smartphones and other hand-held devices. The additional sensor system can be integrated directly in the drive, which allows for a simple technical implementation. The measured acceleration signal can further be used for the compensation of disturbance forces, providing the possibility to further improve the operating be-havior.
