Sequential Linearization as an Approach to Real-Time Marine Gas Turbine Simulation

A real-time marine gas turbine simulation would offer an essential basis for advanced marine propulsion control designs. Such designs may be realized as model reference controllers and/or health monitoring controllers. This paper presents an approach to real-time turbine simulation, using a method of sequential state space linearizations. The linearizations are shown to be simple enough to be computed in real time. Comparisons between simulations and experiments are presented and discussed. The approach is shown to have very good accuracy for both transient and steady-state predictions.
