摘要
应用 Lon Works 技术构建一个计算机控制系统,可同时对四台 PTFE 成型烧结炉烧结工艺实施控制。控制算法根据系统误差及其变化率的大小自动选择通断控制、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%,可很好实现对烧结温度、烧结时间、冷却速率等烧结工艺条件的精确控制。
To adopt LonWorks technique forms a fieldbus microcomputer control system which can achieve four PTFE（Polytetrafluoroethylene） molding sintering furnace temperature control at the same time. System control arithmetic can choices 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 etc.
