Abstract
An embodiment of a control system includes a current command module configured to receive a torque command and output a current command for controlling a direct current (DC) motor, and a current capability limiting module configured to receive the current command and a current limit indicating a maximum motor current, limit the current command based on the current limit, and actively further limit the current command based on a capability limit value.
Claims20
A control system, comprising:
- a current command module configured to receive a torque command and output a current command for controlling a direct current (DC) motor;
- and
- a current capability limiting module configured to receive the current command and a current limit indicating a maximum motor current, limit the current command based on the current limit, and actively further limit the current command based on a capability limit value.
A method of controlling a direct current (DC) motor, comprising:
- receiving a torque command and generating a current command by a current command module;
- receiving the current command and a current limit at a current capability limiting module, the current limit indicating a maximum electrical current;
- limiting the current command based on the current limit;
- and
- actively further limiting the current command based on a capability limit value.
