Gas Turbine Propulsion Plant Control

摘要

A model of a gas turbine variable pitch propeller propulsion system for a warship is considered. The system inputs, for control purposes, are demanded fuel flow and propeller pitch angle. The principal output which is to be regulated is the propulsion shaft speed while shaft torque changes are to be suitably confined. An optimum, multivariable, minimum control effort regulation strategy is proposed enabling improved transient and constrained output interaction to be achieved. Simple passive feedback elements are employed. System regulation at full and half power is investigated.
