摘要
传统的干燥控制系统思维方式是把干燥流程看成是一个大的惯性场,以惯性的形态看待与过程相关的数据,对输入参数的过程实时性很少研究,这样的结果就是控制准确性、精确度与实际过程的吻合程度较差。拟从干燥系统输入体系的结构入手,采用时序分析的手法对入粮到干燥的传输时序进行解析,推理出动态实时数据模型。
In the traditional control system of dryers, it＇s considered that the drying process is inertial, that means the parameters are thought as stationary but in fact they are real-time variable. It results that the control accuracy can＇t match the real dynamic process. In this paper, the time sequence method was adopted to analyze the input construction of control system and the parameter transfer process and set up a model with real-time dynamic data.
