Abstract
A method includes generating a first feedforward signal based, at least in part, on a sensor signal. The method further includes generating a second feedforward signal based, at least in part, on a feedforward seek table. A control signal is modified based, at least in part, on the first feedforward signal and the second feedforward signal. A position of an actuator is controlled in response to the modified control signal.
