摘要

In this paper, an alternative approach of model-based control method called Behavior Model Control (BMC) is introduced. The BMC is designed to control processes that are often characterized by the robustness problem. The interesting feature of BMC control scheme is that it induces supplementary control inputs, which yield the process to follow the process model. This feature leads to great robustness of the closed loop system in face of certain amount of process dynamic variations. This is due to the fact that the tuning of the main controller is based on the defined process model which has known and non vary ing parameters. Most applications of BMC published so far are limited only to applications related to electrical drives. The BMC, in the present work, has been extended to control the air temperature inside a duct of the process trainer. Such process trainer is referred by the abbreviation (PT36). Note that PT36 has the basic characteristic of a large chemical process, enabling distance/velocity lag and transfer lag. Experimental results show that BMC yields better results than a conventional feedback controller. Control algorithms are implemented using Labview software as a control platform.
