Global Nonlinear Modelling of Gas Turbine Dynamics Using Narmax Structures
This paper examines the estimation of a global nonlinear gas turbine model using NARMAX techniques. Linear models estimated on small-signal data are first examined and the need for a global nonlinear model is established. A nonparametric analysis of the engine nonlinearity is then performed in the time and frequency domains. The information obtained from the linear modelling and nonlinear analy...
متن کاملNonlinear Gas Turbine Computer Modelling using NARMAX structures
This paper provides a comparison of techniques used to model the fuel flow to shaft speed relationship of a Spey gas turbine engine. Linear models are examined and the need for nonlinear modelling is justified. A technique based on nonparametric data analysis is proposed, to simplify the identification of a nonlinear model of the engine. A NARMAX model is identified and its performance validate...

15 صفحه اولSimulations of ARMA and ARMAX Models for a Machining Process
The needs of accuracy of machines are strictly increasing for the manufacturing processes. It is costly to use high precision machine to achieve the goal. Therefore, if the forecasting of errors can be obtained from the gathered past error values, it allows the control system to compensate the errors. In this paper, the simulations of manufacturing processes are using the ARMA and ARMAX models....
متن کاملon the relationship between using discourse markers and the quality of expository and argumentative academic writing of iranian english majors
the aim of the present study was to investigate the frequency and the type of discourse markers used in the argumentative and expository writings of iranian efl learners and the differences between these text features in the two essay genres. the study also aimed at examining the influence of the use of discourse markers on the participants’ writing quality. to this end the discourse markers us...
