摘　　要：自动络筒机系统是一个复杂的非线性、时变、多干扰、多学科交叉的系统。自动络筒机运行时,每个槽筒工作均需负压,且各槽筒工作相互独立、随机,互不相关,对它建模非常复杂。为此,文中提出整个负压风道简化模型,将各槽筒上的不定时开放的气孔看作干扰,由控制系统解决。针对所提模型设计了增量式PID控制器,并利用仿真实验以及现场实验验证了该控制器的有效性,解决了负压吸风系统风道压力按需平衡供给问题,在满足络纱工艺需要的前提下,使高速自动络筒机负压吸风系统平稳运行。The automatic winder system is a complex nonlinear, time-varying, multi-interference and multidisciplinary system. When the automatic winder running, all grooved drum required negative pressure, and each the grooved drum work independently from each other, random and unrelated, and it is very complex to model this whole negative pressure duct; thus the simplified model is proposed, the grooved drum treated as disturbance, the incre- mental PID controller has been designed based on the model derived, the simulation and on-site experiments has veri- fied the effectiveness of the controller and the correctness of model derived and settled the negative pressure suction duct pressure balance problem and realized automatic winder negative pressure suction system smoothly running.
