Method and apparatus for providing feedforward control of two interacting actuators

摘要

A method and apparatus for providing feedforward control of two interacting actuators to compensate for interaction there between is disclosed. State models for each actuator that processes acceleration for each actuator provide an estimate of head acceleration for each of the actuators and to provide feedforward control signals to the actuators for controlling the positioning of the heads based upon the estimates of head acceleration for each of the actuators.
