摘要：
This paper considers dual-stage actuator control system design and demonstrates resulting servo performance improvements. A discrete-time dual-stage actuator control system is proposed along with a design technique to attain a very small destructive interference with satisfactory time and frequency responses, which is used for track follow, track seek in the microactuator range, and settle. Application results are provided to demonstrate usefulness of the proposed dual-stage actuator control system and the design technique.
