Abstract
A system and method for motor control includes at least one dynamic offset value provided to a motor drive. Each dynamic offset value is determined by an external processing device and transmitted to the motor drive. The external processing device includes a rigid-body model of the motor and of the load controlled by the motor to generate each dynamic offset value. The dynamic offset value may be a position, velocity, or torque offset signal or a combination thereof. Each dynamic offset value and the desired motion profile are provided at a first update rate. The system control loops execute at a second update rate faster than the first update rate. Each dynamic offset value and the reference command are interpolated to generate values for each period of the second update rate. The interpolated values are provided to the system control loops to achieve desired performance of the motor.
