Abstract
In an example embodiment, an electric drive system includes an inverter configured to convert a direct current (DC) voltage into an alternating current (AC) voltage for an electric machine; processing circuitry configured to cause the electric drive system to obtain parameters of the electric machine, obtain a mode of operation for the electric machine, the mode of operation related to at least one of noise, vibration and harshness, and control the electric machine based on the parameters of the electric machine and the obtained mode of operation.
Claims20
An electric drive system comprising:
- an inverter configured to convert a direct current (DC) voltage into an alternating current (AC) voltage for an electric machine;
- and
- processing circuitry configured to cause the electric drive system to,
- obtain parameters of the electric machine,
- obtain a mode of operation for the electric machine, the mode of operation related to at least one of noise, vibration or harshness, and
- control the electric machine based on the parameters of the electric machine and the obtained mode of operation.
A method of controlling an electric drive system, the method comprising:
- obtaining parameters of an electric machine of the electric drive system;
- obtaining a mode of operation for the electric machine, the mode of operation related to at least one of noise, vibration or harshness;
- and
- controlling the electric machine based on the parameters of the electric machine and the obtained mode of operation.
