摘要
为了提高加弹机温度控制系统(TCS)的控制精度和减小其设计复杂程度,提出了一种基于自校正比例-积分-微分(PID)控制技术的加弹机TCS实现方法.根据温控对象的结构特点以及工作环境,利用热力学原理建立了离散数学模型.通过极点配置方法设计了加弹机温控器自校正PID最小相位控制系统.利用递推最小二乘法进行了系统系数辨识,并引入遗忘因子以提高TCS的模型跟踪性能.实验以及工业现场应用表明,该方法设计和实现较为简单,能够满足加弹机TCS的多通道要求,温控偏差可以控制在±1%以下.
To improve the control precision of texturing machine temperature control system （TCS） and reduce its design complexity, a texturing machine TCS realization method based on self-turning proportionintegration-differential （PID） was put forward. According to the structure characteristic and working environment of temperature control object, the object＇s discrete mathematics model was established using thermodynamics principle. The self-turning PID minimum phase control system for texturing machine temperature controller was designed using pole points placement method. System parameters were identified by adapting recursion least square method, and the forgetting factor was introduced to improve the model tracing ability of TCS. Experiments results and industry field application show that the method designs can be realized simply, and can satisfy the multi-channel requirement of texturing machine TCS, and that the temperature control deviation can be limited to under±1%.
