摘要
针对加弹机温控系统通道数目多、精度要求高、影响因素复杂等问题,在对当前温度控制所采用的方法进行广泛调研的基础上,提出了一种基于自校正PID控制技术的加弹机温控方法。分析了加弹机温度控制的特殊性,阐述了现有温度控制的一般处理方法及存在的问题,并指出自校正PID控制技术的优势。运用热力学方程建立温控对象的离散数学模型,并对模型参数辨识进行了深入探讨,利用极点配置方法设计了温控器,给出了加弹机温控系统的实施方案。工业现场实验证明该系统实用有效,精度满足要求。
In allusion to such problems of texturing machine temperature control system as large numbers of control channel, high precision demand, complex influencing factor etc., a temperature control method based on self-turning PID for texturing machine was put forward after making an extensive investigation of the available methods used for temperature control. The trait of texturing machine heating chest was presented ; the present temperature control methods were expounded along with the existing problems and the superiority of self-turning PID control was emphasized. Discrete mathematics model was established by the way of the thermodynamics formula, and its model parameters' recognition was discussed. The design method of pole placement controller was described and implementation scheme for texturing machine was given. Commercial trials have proved that this temperature control system is satisfactory, and can reach the required control precision.
