Simplified Dynamic Model of the T700 Turboshaft Engine

摘要

A simplified open-loop dynamic model of the T700 turboshaft engine, valid withinthe normal operating range of the engine, is developed. This model is obtained by linking linear state space models determined at different engine operating points. Each linear model is developed from a detailed nonlinear engine simulation using a multivariable system identification and realization method. The simplified model may be used with a model-based real time diagnostic scheme for fault detection and diagnostics, as well as for open loop engine dynamics studies and closed loop control analysis utilizing a user generated control law.
