Different assembly, printing and cutting applications demand often fully synchronized movement of multiple actuators. The linear tooth belt drive offers an inexpensive and fast solution for linear movement applications. In this paper the cross-coupled controller is implemented and tested with biaxial linear tooth belt drive system for motion synchronization. The elastic tooth belt set uncertainty in the system parameters and the quantitative feedback theory is applied to design controllers for the biaxial system. Due to an elastic belt stretching phenomena system accuracy is analyzed using two different feedbacks with cross-coupled controller -firstly values are measured from driving motors' encoders and secondly from belt drives' load carts.
The purpose of this work is to determine the applicability of the ZigBee technology to electric motor rotor measurements. Requirements for data transmission, electrical structure and powering of a sensor are discussed. A prototype wireless ZigBee-based torque sensor is built and tested. The results of the tests are analyzed.
Tooth belt drives with directly connected permanent magnet servo motors are mechanically very flexible systems, and the resonances of the system change significantly as function of cart position and load. This paper addresses issues in identification of a linear tooth belt-drive with limited stroke. Particular attention is paid to detecting the changes in the system dynamics. This is achieved by using recursive least squares algorithm and exciting the system in different cart positions in order to identify the varying dynamics. Moreover, the direct identification in open-loop as well as under closed-loop conditions is considered. The identification of linear tooth belt drive is evaluated by simulations as well as through experimental tests.
