THE HARDWARE-IN-THE-LOOP SIMULATION STUDY ON THE CONTROL STRATEGY OF GAS TURBINE

摘要

A 3-shaft gas turbine engine for ship propulsion was taken as an object to establish the hardware-in-the-loop simulation system, which is composed of computers, real physical parts, measuring instruments, interfaces between physical parts and computers, and the network for communication, as well as the relevant software including mathematical models of the gas turbine engine. "Hardware-in-the-loop" and "volume inertia effects" are the two major features of this simulation system. In comparison with traditional methods for gas turbine simulation, the new simulation platform can implement simulation in real time and also can test the real physical parts performance through integration of the real physical parts and the mathematical model in a computer.
