摘要
以工业过程中具有纯滞后的一阶惯性环节为对象,针对Smith预估器对干扰信号适应能力较差的弱点,从结构上加以改进,使调节效果明显改善。
In order to overcome the disadvantage of Smith estimator.i.e. the weak ability of adaptation to the interference signals, the structure of the estimator is improved. The control result is improved obviously on the object of 1st order inertia element with dead time.
