基于变参数智能控制的多电机同步控制系统

Multi-motor synchronization system based on variable gain intelligent control

在常规PID控制的基础上提出了适用于多台电动机同步传动的变参数智能控制方法,并以宽幅织物热定型机的拉伸张力与同步控制系统为例,采用PLC控制器实现,其程序设计简单,安装接线简单.系统运行证明,此系统具有相应快、无超调和无稳态误差的特点,可广泛应用于纺织、染整、造纸的拉伸以及机械生产线的电机同步控制中.

Basing on the conventional PID algorithmic, a variable gain intelligence control scheme is proposed. Consequently, this new idea is implemented by PLC controller in the stretch tension and synchronization control system of a wide-fabric heating-shaping machine. Such system has such characteristics as rapid response, overshoot-less and no steady-state errors. The proposed scheme may be widely suitable for electrical motor synchronization control demands arising from the spinnery, paper mill and mechanical production lines.
