烟草制丝中试线加料机控制策略设计及其仿真

Control Strategies and Simulation for Feeding Machine in Silk Making Testing Line of Tobacco Factory

烟草制丝中试线具有流量小、配方多样、生产周期短等特点。本文提出了基于串级、前馈、比值等复杂控制策略的中试线加料机控制系统,搭建了基于OPC通信技术实验仿真平台。实验结果表明,复杂控制策略可以较好的克服生产过程的扰动。设计的实验平台可用于工程技术人员现场投运前对控制算法和顺序逻辑控制进行验证,对提高加料机的控制效果具有指导意义。

Silk making testing line have some characters such as small flow rate, multi-prescription, short production period. The paper presented testing line feeding machine control system based on cascade control, feedforward control ratio control and other complex control strategies, and built up the simulation platform is founded based on OPC technology. The results of simulation showed that those control strategies can overcome the disturbance from testing line. The designed experimental platform can be used for technicians to verify control algorithm and sequence logic control before putting into operation on the spot, thus has guiding meaning to improve the ability of control system for feeding machine.
