Abstract:
1. A system comprising: a control module configured to generate a first signal to control a speed of an actuator arm as the actuator arm is loaded from a parked position to an edge of a rotating storage medium; and an estimating module including wherein the estimating module is configured to (i) estimate a force to be applied to the actuator arm to move the actuator arm from the parked position and (ii) generate an estimated force signal based on (i) the first filtered output and (ii) the second filtered output, wherein when the actuator arm is in the parked position, the control module and the estimating module respectively generate the first signal and the estimated force signal based on a first input that moves the actuator arm from the parked position, and wherein the first input is generated based on a proportional distribution of a second input that loads the actuator arm on the rotating storage medium.
