摘要：
Refrigerating evaporator superheat has the characteristics of the large time delay and superheat model is uneasy to determine. But the general smith control has bad robustness and require a high model accuracy. The paper introduces a self-adaptive smith control way, this method can dynamically amend the estimated output through historical estimated Result, which can improve the predicting accuracy. Applying this control way to the evaporator superheat system, the control quality is improved, system runs stably, anti-interference performance improved and also the system's robustness.
