Abstract
A motor controller that controls a motor in a first control method based on a first current command value and a second control method based on a second current command value. The motor controller includes an analog-to-digital converter to generate the second current command value based on a reference signal externally input to the motor controller and a current limit generator to generate an upper limit value of the first current command value based on the second current command value.
Claims18
A motor controller to control a motor comprising:
- a first current command value generator to generate a first current command value;
- an analog-to-digital converter to generate a second current command value based on a reference signal externally input to the motor controller;
- and
- a current limit generator to generate an upper limit value of the first current command value based on the second current command value,
- wherein the motor controller controls the motor in a first control method based on the first current command value and a second control method based on the second current command value.
A method of controlling a motor with a motor controller by using a first control method and a second control method, comprising:
- generating a first current command value;
- receiving a reference signal externally input to the motor controller;
- generating a second current command value with an analog-to-digital converter based on the reference signal;
- generating an upper limit value of the first current command value with a current limit generator based on the second current command value;
- and
- alternately implementing the first control method and the second control method based on the upper limit value of the first current command value and the second current command value, respectively.
