Abstract

A motor controller that is operable to control a motor includes drive current generation circuitry having an output coupled to the motor. The motor controller further includes a velocity control path. The velocity control path includes angular velocity estimation circuitry having an input adapted to be coupled to the motor, a velocity comparator having first input coupled to a target velocity input and a second input coupled to an output of the angular velocity estimation circuitry, and an adaptive velocity controller having a first input coupled to an output of the velocity comparator and having an output coupled to a first input of the drive current generation circuitry. The motor controller further includes controller parameter determination circuitry having a first input coupled to the output of the angular velocity estimation circuitry and having an output coupled to a second input of the adaptive velocity controller.
