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

在本研究项目中，提出了一种补偿齿轮齿条进给驱动生产机床侧隙的新方法。目标是通过产生基于机床滑橇测量加速度的补偿信号来提高定位精度和进给驱动的控制质量。状态变量的测量是使用低成本的mems加速度计实现的，这种加速度计广泛应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在驱动器中，这允许一个简单的技术实现。测量到的加速度信号可以进一步用于补偿扰动力，为进一步改善工作性能提供了可能。

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.
