Abstract :
Stepping motors are normally operated without feedback and may suffer from loss of synchronisation. This can be prevented by the use of positional feedback. A simple control algorithm is developed which allows a stepping motor to operate effectively in open-loop mode as long as it remains synchronised, but which recovers from loss of synchronisation following a disturbance. The control algorithm can be implemented as four interconnected state machines, an up/down counter and a rate meter
