史密斯预估位式调节器及其应用的研究

Research on Smith Prediction On-Off Controller and Its Application

针对非线性位式调节系统存在持续振荡、控制精度低的问题,将史密斯预估器推广到非线性位式调节系统,提出史密斯预估位式调节器,并给出了在温度控制系统中的实现方法。通过在烤漆生产线上的电阻炉的实验应用,显示史密斯预估位式调节器能有效抑制纯滞后造成的非线性位式控制系统的持续振荡,有效提高位式温度控制系统的控制精度。

Aim at the accuracy of no-linear position control system,spread Smith predictor to no-linear on-off control system,present Smith prediction on-off controller and give out its realization on temperature control system.Using the application on baking paint stove,it appears that smith prediction on-off controller can reduce the oscillation value of on-off control system and improve the accuracy effectively.
