G0801-1-3 Control of two shaft axial micro gas turbine generator system based on dynamic model

Abstract

In this study, to establish the methodology for controlling the rotational speed of two shaft axial micro gas turbine generator system, modeling strategy of static and dynamic characteristics of the system based on nonlinear model is proposed. This model is constructed based on the combination of measured data and correction factors and does not rely on compressor and turbine map, which yields better prediction results with higher accuracy. To investigate the stability and robustness of the system, H infinity algorithm is employed as a system controller. The difference on controller performance designed based on the dynamical modeling of the target system and the measured data is discussed.
