摘要: 针对加弹机温控系统的纯滞后问题,采用Smith预估器对系统进行补偿。详细介绍了加弹机温控系统控制模型的建立与应用,并给出了系统的流程图。后向通道采用了调功器控制原理,简化了硬件电路,提高了设备的功率因数。对Smith补偿控制系统和普通PID控制进行了比较。结果表明,Smith补偿控制系统可以消除系统的纯滞后时间,减小超调,缩短调节时间,控制精度高,系统运行稳定,其性能优于普通的PID控制系统,适合在加弹机中使用该技术。

Abstract: Aiming at the problem of large delay in temperature control of draw texturing machine,a method of Smith predicting control was used.The building and application of the temperature control model of draw texturing machine were discussed in detail,and its flow chart was presented.The control principle of thyratron power regulator was used in the back channel,thus,the hardware was simplified,and the power factor was raised.Comparison of Smith predictor control system and PID control system demonstrated that the former can eliminate the pure time delay,reduce overshoot,shorten regulating time,and improve control precision and running stability.It is obvious that Smith predictor control system is superior to the conventional PID and suitable for the temperature control of draw texturing machine.
