Stabilization of V94.2 Gas Turbine Using Intelligent Fuzzy Controller Optimized by the Genetic Algorithm

摘要

AbstractAccording to the crucial role of gas turbines in electricity production without significant harmful effects on the environment, this paper is aimed at the modeling and simulation of a particular type of these systems known as V94.2. Gas turbine is an instrument for power generation, which is capable of producing a vast amount of energy by considering its size and weight. Despite all the advantages and applications of gas turbines, the use of these systems is not free of difficulties because of their remote controls in such a way that it is estimated that about a quarter of turbine price is spent on its launching. To tackle this problem, a mathematical model has been proposed for V94.2 gas turbines as a result of the review of the pieces of research done on the modelling of gas turbines in the past few years and on the basis of Rowen model. In the following, the capability of fuzzy controllers has been used to ensure the system stability. In addition, an intelligent genetic algorithm has been added to the control structure in order to optimize the proposed control system as well as obviating the need of fuzzy control to the experts’ information about the system. The results of the simulation in MATLAB software clearly shows that the output variables of V94.2 gas turbine reach a specific situation and place after applying the inputs at the right time.
