Abstract
A method for driving an electric motor includes providing two controllers for driving the electric motor. The two controllers use different control methods to drive the electric motor. The method further includes selecting a first controller of the controllers as a primary controller to drive the electric motor and a second controller of the controllers as a secondary controller, monitoring a control of the electric motor, and switching the control of the electric motor from the primary controller to the secondary controller if an error condition is detected in the control of the electric motor.

A method for driving an electric motor, comprising:
- providing two controllers for driving the electric motor, the two controllers using different control methods to drive the electric motor;
- selecting a first controller of the controllers as a primary controller to drive the electric motor and a second controller of the controllers as a secondary controller;
- monitoring a control of the electric motor;
- and
- switching the control of the electric motor from the primary controller to the secondary controller if an error condition is detected in the control of the electric motor.
A system for driving an electric motor, comprising:
- two controllers for driving the electric motor, wherein the two controllers use different control methods to drive the electric motor and are configured to:
- select a first controller of the controllers as a primary controller to drive the electric motor and a second controller of the controllers as a secondary controller;
- monitor a control of the electric motor;
- and
- switch the control of the electric motor from the primary controller to the secondary controller if an error condition is detected in the control of the electric motor.
