We present a design approach using μ- synthesis which returns a controller in observor/state-feedback form with physically meaningful states. The advantages of this physics-based approach are illustrated by a detailed outline of the controller design for Woodward governor's GS16 turbine gas metering valve.
The current mu-synthesis tools are not directly suitable for industrial turbine fuel and water control because they lead to high-order controllers with physically meaningless states. The production valve example here is the Woodward GS6 Turbine Gas Metering Valve that has a single-phase permanent magnet motor coupled by a shaft to an inertia disc and a gas metering shoe with a high level of dry (nonlinear)...
We present a system where visualization and the control of the simulation are integrated to facilitate interactive exploration and modeling of large data sets. The system was developed to estimate properties of the atmosphere of Venus from comparison between measured and simulated data. Reuse of results, distributed computing, and multiple views on the data were the major ingredients to create an...
