Abstract :
The performance of a multi-motor system with a single common closed-loop has been investigated with particular reference to a two-motor system. The system was found to be unstable, with the velocities of the motors oscillating with increasing amplitude. The origin of the oscillations is discussed and methods for their elimination are presented. In conclusion, it is evident that the simple control strategy used is inadequate for stable operation of a multi-motor system.
