ABSTRACT
This study gives a detailed account about the adaptation of an intelligent gas flow controller for non-linear application. Before elaborating the design of the process-specific adaptive scheme for fuzzy gas flow controller, it describes how to develop the mathematical model of gaseous system and study of non-linearity. In the latter part, the proposed controller is developed and its performance is compared to PID and conventional fuzzy controllers. In the present work, the performance of the proposed controller is tested with the help of MATLAB simulations. Instead of using a fixed gain multiplier, finding an appropriate multiplying factor for the fine tuning of Fuzzy Logic Controller becomes a great challenge, which is directly related to the process dynamics. In view of this, a non-fuzzy adaptive scheme is implemented for the proposed fuzzy gas flow controller. Effectiveness of the proposed self-adaptive fuzzy controller is reviewed in non-linear gas flow control.
