Title:
LINEAR CONTROL SYSTEMS AND METHODS FOR AVOIDING MOTOR IN DC MOTOR
Document Type and Number:
WIPO Patent Application WO2004102783
Kind Code:
A3
Abstract:
A linear power controller and related circuitry may be implemented to provide linear control of a variable DC electric motor. The controller and motor are coupled to form a closed loop for controlling the speed of the motor and for adjusting or compensating for noise and other characteristics having a negative impact on performance. The circuitry is configured to have a crossover frequency that is below the motor noise frequency. The configuration of the crossover frequency may allow for the motor or the controller to be implemented without additional circuitry to filter or compensate for motor noise.
