Novel position estimators for timing belt drivers

Kilic E., Dolen M., Koku B., Dogruer C.

Journal of Automation Mobile Robotics and Intelligent Systems

2007

Vol. 1, No. 2

55-61

This paper focuses on viable position estimation schemes for timing belt drives where the position of the carriage (load) is to be calculated via reference models accepting input from a position sensor on the actuator of the timing belt. A detailied analysis on the source of transmission errors is presented a number of relevant mathematical modeis are developed utilizing a priori knowledge on the process. The paper illustrates that such schemes are very effective when the drive system is not subjected to external loads es well as widely changing operating conditions such as ambient temperature, belt tension.

Nonlinear position estimators based on artificial neural networks for low costs manufacturing systems

Dogruer C., Kilic E., Dolen M., Koku B.

Journal of Automation Mobile Robotics and Intelligent Systems

2007

Vol. 1, No. 2

40-44

The accurate contral of CNC machine axis requires relatively expensive direct measurement sensors. In this paper, artificial neural network based position error estimators are comparatively evaluated as a part of a low-cost (but high performance) manufacturing system. Such schemes are very effective when the system is rot subjected to external loads as well as widely changing operating conditions such as ambient temperature.
