Comments on "Minimizing power dissipation in a disk file actuator" by E.S. Cooper

The seek control problem that arises in the abovementioned work (see ibid., vol.24, p.2081-91, 1988) is formulated as an optimal control problem with constraints relating directly to specified design limits on input magnitude and power dissipation. The resulting control is optimal for a given peak-to-average power ratio. Power-optimal control and time-optimal control are special cases of this type of control.<
