ADVANCES IN TURBO ENGINE REAL-TIME SIMULATION FOR MODERN CONTROL SYSTEM DEVELOPMENT
2000
The available computational power is constantly increasing. This facilitates detailed simulations of turbo engine dynamical behavior in real-time with a high sampling rate. These simulations can include secondary effects as well as failure cases. This paper first gives an overview and a comparison of the most common simulation methods. Special real-time issues will be discussed. Following this, examples will be given of how real-time engine simulations can be used for the development of engine control systems. One main application described is rapid prototyping of control systems for helicopter engines as performed at the Chair of Flight Propulsion. The other application described is the design of control systems including onboard engine models. The advantages of such an approach for highly integrated hypersonic engines, to be used in the lower stage of a planned two-stage-to-orbit vehicle, will be discussed.
