Ac Drive Synchronization Using CAN Protocol

In spinning industry, AC-drives are needed to rotate in synchronized speed to achieve quality product. Because of the quick evolution of manufacturing processes, the demand for flexible automation systems is on the rise. To meet these, distributed motion control architecture based on intelligent drives and field bus communication tends more and more to replace the traditional solutions. Drive synchronization is necessary in industries where minor difference in rotary movement make major difference in product quality. Using CAN (Control Area Network) protocol we can drive multiple motor in synchronization with minimum transmission gap. A control area network (CAN) based multi-motor synchronized motion control system with an advanced synchronized control strategy is proposed. The strategy is to incorporate the adjacent crosscoupling control strategy into the sliding mode control architecture. In this project we are going to synchronize multiple AC motors using CAN protocol.
