Abstract

In this paper, we develop a nonlinear performance based model for a twin spool turboshaft engine which drives a variable pitch propeller. We also develop a piecewise linear representation of the model, which can be used for control of the turboshaft engine for large throttle commands (i.e. for the entire flight envelope). Finally we develop a decentralized piecewise representation of the model suitable for distributed and decentralized engine control. Simulation results for decentralized piecewise linear control of JetCat SPT5 turboshaft engine are presented. Fuel flow is the control input for the engine core subsystem, and prop pitch angle is the control input for the engine fan/prop subsystem. © 2011 by the American Institute of Aeronautics and Astronautics, Inc.
