摘　　要：通过分析胶槽内胶液温度变化与手模沾胶质量的关系,以及影响胶槽内胶液温度变化的因素,明确了控制对象的特性。结合生产要求,通过软件方法将PID计算输出的连续结果作离散处理,实现了以开关型阀门为执行机构,对PVC手套生产中胶槽内胶液温度的周期性调节。实际应用效果验证了PID后续处理算法的正确性和系统方案的可行性。Through analyzing relationship between glue temperature in tank and glue quality and the factors which influencing tank temperature,the controlled object properties were defined;and taking into account the production requirement,the successive results of PID calculation were discretized with special software to periodically control glue temperature in tank by taking an on-off valve as actuator in PVC gloves production.The application in practice proves validity of PID subsequent algorithm and the feasibility of system scheme.
