Variable Gain Intelligent Control of Multi-motor Synchronization System

Multi-motor synchronization control (MSC) is a key issue in industrial production. Based on the conventional PID algorithmic, a variable gain intelligence control scheme is proposed in this paper. Consequently, this new idea was implemented by PLC controller in the stretch tension & synchronization control system of a wide-fabric heating-shaping machine. Such a system has perfect characteristics, e.g. rapid response, overshoot-less and no steady-state errors. In addition, easy programming, simple wiring and strong anti-jamming ability lead to a stable operating performance. The proposed scheme can be widely used in electrical motor synchronization control demands arising from the spinnery, paper mill and mechanical production lines.
