Model Order Reduction of Electrical Machines With Multiple Inputs

Model Order Reduction for Rotating Electrical Machines

The simulation of electric rotating machines is both computationally expensive and memory intensive. To overcome these costs, model order reduction techniques can be applied. The focus of this contribution is especially on machines that contain non-symmetric components. These are usually introduced during the mass production process and are modeled by small perturbations in the geometry (e.g., ...

Balanced Truncation Model Order Reduction for LTI Systems with many Inputs or Outputs

We discuss balanced truncation (BT) based methods for model order reduction (MOR) of linear time invariant (LTI) systems with many input or many output terminals. Applying BT methods makes it necessary to balance the system, which is equivalent to finding the controllability and observability Gramian of the system in a special diagonal form. The Cholesky factors of these Gramians are efficientl...

Transformation of passive electrical networks with distributed PWL-sources using a Model Order Reduction

In modeling of distributed systems with distributed sources large networks with RLC-elements and independent sources arise. This high complexity leads to a high effort in simulations. Therefore model reduction can be used to reduce these networks, preserving the behavior at the observed nodes in the networks. For the reduction of networks with a large number of independent sources only a weak r...
