多分部纸机传动控制器的研究

The research of multi-branches paper machine drive controller

针对造纸机传动控制系统中不同型号变频器之间能否替代的问题,设计出一种多分部纸机传动控制器.传动系统可以用不同型号变频器组成,不论开环和闭环可以任意组合,克服了传统的控制方式中采用集成运算放大器构成模拟式速度链或伺服电动机联动速度链,其在运行时存在漂移、操作不便等缺陷.在实际造纸机传动系统设计中获得了广泛的应用,取得了良好的控制效果.

Aiming at the problem of whether different models inverter can replace for each other in paper machine drive control system,this article designs a multi-branches paper machine drive controller.The drive system can use different models inverters,both open and closed loop can be any combination.The traditional control method has the problem of drift and inconvenient operation during running because of adopted in the integrated operational amplifier analog speed chain or servo motor linkage speed chain,This drive system can overcome it.It has obtained the widespread application and good control effect in the actual paper machine drive system design.
