Abstract: Method and apparatus for control object manipulation from an initial position to a final position. A jerk control profile describes a near time-optimal jerk trajectory for the control object and includes a sequence of first, second and third sinusoidal pulses of respectively alternating polarity and common absolute magnitude. The area of the second pulse is nominally equal to the combined area of the first and third pulses, and the pulses are preferably symmetric about the respective maximum pulse values. Associated control profiles (control voltage, current, velocity, displacement, etc.) are derived from the jerk control profile. For longer seeks, constant, non-zero jerk segments are inserted into the profile between the pulses, during which control voltage is maintained near saturation. The control object preferably comprises a transducer in a data storage device and the jerk control profile is stored in a memory location of the device.
