Abstract

A motor drive monitors operation of a motor and adaptively track disturbances experienced by the motor. The motor drive receives a command signal and a cycle position signal. An estimated disturbance observed throughout a cycle of operation is stored in a look up table, and the motor drive uses the stored values as a feedforward value into a control module. The motor drive adaptively monitors operation of the motor and generates a new estimated disturbance value throughout each subsequent cycle of operation. The values of the estimated disturbance are updated within the look up table as a function of the new estimated disturbance values and of the previously stored values. The stored disturbance values adaptively track cyclic disturbances in the controlled machine or process and to reduce the effects of these cyclic disturbances on tracking error in the controlled machine or process.
