Abstract
The real time simulation model is the key point for the debug and checking of the controller for gas turbine engine.The conventional transfer function model can not reflect the interaction among different variables.According to the volume inertia method and object-oriented technique,one nonlinear dynamic model of V94.3 gas turbines was built up based on Matlab/Simulink simulation platform and the dynamic characteristics were analyzed.In the light of the gas turbine speed regulation and load control,the controller module was established.Simulations were eventually performed for control performance,which can supply references to the design of control system of V94.3 gas turbine.
