Patent Images
1. A method for controlling a motor comprising:
- controlling the motor in response to a first adaptive control method during a first phase of motor operation, wherein the first phase is an acceleration phase, wherein controlling the motor in response to the first adaptive control method comprises measuring a first motor speed, determining a first control value using the first motor speed, and providing a first input signal to the motor based on the first control value; and
controlling the motor in response to a second adaptive control method during a second phase of motor operation, wherein controlling the motor in response to the second adaptive control method comprises measuring a second motor speed, determining a second control value using the second motor speed, and providing a second input signal to the motor based on the second control value.

Abstract
A different adaptive control method is used to control a motor during each of two or more phases of motor operation. Thus, in a first phase of motor operation the motor is controlled using a first adaptive control method, in a second phase of motor operation the motor is controlled using a second adaptive control method, and so forth. The motor can be controlled in this manner in any number of phases, in which the motor is used for any of a number of corresponding purposes. The method used in each phase can be optimized to suit that type of operation without compromising operation during other phases.
