Abstract

The synchronization between two electrical motors (master and slave) is studied. To reduce the costs of the master–slave combination, the slave motor is mounted with a very low-resolution encoder (one pulse per revolution). Since the position measurements are asynchronous in time, standard control and analysis techniques are not applicable. Two methods are proposed to deal with these cheap, low-resolution encoders: the hybrid and the asynchronous control scheme. The presented controllers are successfully tested on a real industrial master-multi-slave system as is used for mailing machines.
