摘要： 采用LonWorks技术设计现场总线控制系统，可同时对4台PTFE树脂成型烧结炉实施控制。控制算法采用变结构控制器，可根据系统误差及其变化率的大小自适应选择通断控制、模糊控制、积分控制等控制策略。应用效果表明，系统温度控制精度达到±0.5%，可实现对烧结温度、烧结时间、冷却速率等烧结工艺条件的精确控制。

Abstract: This paper introduces a fieldbus microcomputer control system used in PTFE (Polytetrafluoroethylene) molding sintering process. System design adopts LonWorks technique, and the system can achieve 4 PTFE molding sintering furnace temperature control at the same time. System control arithmetic adopts variable-structure-control, which can choose on-off-control and fuzzy-control and integral-control strategy automatically. The application effect shows that the temperature control precision is 0.5%. The system can achieve accurate control to techniques condition of molding sintering process such as sintering temperature, sintering time, cooling speed.
