Description
Summary:Multi-motor arrangements have grown as an important field in the manufacturing process where high-performance applications that are able to achieve precise control of position, speed, acceleration, and deceleration are required. Several approaches exist for such synchronisation control all of them with the main aim to synchronize multiple machine axes and to emulate the actions of the mechanism they replace. However, so far little work has been done in the relative speed and position error between axes during the start-up, shutdown conditions and under load impacts on any motor. This paper present a novel multi-motor synchronisation strategy called relative coupled strategy, which can be easily applied into a real industrial environment. This novel approach is specifically compared with the electronic (virtual) line shaft. Results are presented showing the ability of the novel and current strategies to cope with different load conditions.
