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.

在这个拟议的研究项目中，开发了一种补偿带有齿条和小齿轮进给驱动的生产机器中的齿隙的新方法。目的是通过根据测量的机器滑板加速度生成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高效的 MEMS 加速度计实现的，广泛应用于智能手机和其他手持设备。附加传感器系统可以直接集成在驱动器中，从而实现简单的技术实施。测得的加速度信号还可用于补偿扰动力，从而为进一步改善操作行为提供了可能性。
