Identification of a two shaft gas turbine using multi model with single input and multiple output: Decoupled state approach

摘要

The start up of a control approach of an industrial gas turbine requires the use of reliable mathematical models that can be used in regulation. The objective of this work is to identify and model the dynamics of a two-shaft gas turbine, based on single input and multiple output multi-model approach identification with decoupled state from real data, in order to approximate the parameters of system examined by integrating an identification method using the multi model approach to the gas turbine with several outputs from the actual data of the rotational speed, the temperature of the combustion chamber and the exhaust temperature. The obtained results clearly show the effectiveness of this approach in the startup of the examined gas turbine.
