摘要：AbstractIn this paper, a first principles based mathematical model of a laboratory SR-30 engine is developed using the state variable method. The aim is to utilize the model to obtain the shaft speed (RPM) response with fuel flow as input. The objective is fulfilled by utilizing approximated maps and generic governing equations that describe the engine behavior. The mathematical model captures both the steady state and transient behavior of the engine. In addition, the model incorporates actuator dynamics to enable control related studies. A simulator with a graphical user interface is then developed in the Simulink environment. The steady state and transient simulation results are validated against experimental data obtained from the laboratory SR-30 engine. The simulation results are found to be in good agreement with the experimental data. The developed simulator can now be used for further studies such as control design.
