Abstract
A system includes a first module that: receives the output current from the electric motor as a feedback, the output current including a direct axis component and a quadrature axis component; and generates a first voltage command based on a virtual resistance value, the feedback, and a targeted frequency characteristic of the motor control system. The system includes: a second module that: receives a difference between the feedback and a commanded current; and generates a second voltage command based on an estimated inductance value, an estimated resistance value of an electric motor, the virtual resistance value, a targeted frequency response characteristic of the motor control system, and the response of the d-axis component of the output current being decoupled from the response of the q-axis component. The system includes an addition module that generates an input voltage command for the electric motor by adding the first and second voltage commands.
