Uncertain variables, such as electric power system parameters, have significant impacts on dynamic simulations of systems. As traditional uncertainty analysis methods for simulations, both the simulation method and approximation are difficult to balance model complexity, computational efficiency, accuracy. In order accuracy, this paper proposes a based Nataf transformation Gaussian-Hermite quad...

Introducing hydrogen power generation in the industry may contribute to achieve carbon neutrality by 2050. Hydrogen mixed-fuel gas turbines are available, and pure hydrogen-fueled being developed. Meanwhile, systems based on oxygen–hydrogen combustion have been devised. Such system uses as fuel oxygen oxidizer, yielding only water vapor byproduct of combustion. In addition, performs a semi-clos...

H∞ controller for active magnetic bearings (AMBs) with flexible rotor system was designed in this paper. The motion equations of AMBs and flexible rotor system are built based on finite element methods (FEM). Weighting function matrices of H∞ controller for AMBs are studied for both the sensitivity and the complementary sensitivity of H∞ control theory. The simulation shows that the H∞ control ...

This paper presents a methodology for deriving the system graph of a 3D mechanism from CAD models. That is, a linear graph that captures the energy flow in a system. This work is part of a larger research effort in composable simulation. In composable simulation, CAD models of system components are augmented with simulation models describing the component’s dynamic behavior in different energy ...
