Abstract
A control system for a data storage device including a constraint or weight to control stroke utilization and/or closed loop response of the control system. In particular, in one embodiment described, the weight or constraint is used to limit stroke utilization for a microactuator having a smaller stroke than a primary actuator. As described, the constraint or weight is used in conjunction with a mathematical synthesis to synthesize a controller to optimize system performance.
