Claims17
A system comprising:
- a load machine;
- a coupler;
- an electric machine coupled to the load machine via the coupler and configured to drive the load machine;
- and
- a controller configured to
- model the electric machine based on a drive impedance of the electric machine and an impedance of the load machine and the coupler, and
- control the electric machine based on the model.
4 more elements
A method comprising:
- modelling an electric machine based on an identified drive impedance of the electric machine and an identified impedance of a load machine and a coupler;
- and
- driving the load machine based on the model.
A method of modeling an electric machine system, the method comprising:
- obtaining an impedance of an electric machine;
- obtaining an impedance of a coupler and a load machine;
- determining a feedback impedance;
- and
- modeling the electric machine system based on the impedance of the electric machine, the impedance of the coupler and the load machine and the feedback impedance.
