This paper discusses four track-following controller designs for a dual stage hard disk drive system with a slider based piezoelectric micro-actuator. The use of dual stage actuator in hard disk drive system has become a means of achieving increased servo actuator bandwidth. LQG regulator is applied to the compensator design of a dual stage hard disk drive. This paper is described and compared four control system architectures (Parallel loop, Master-Slave, Master-Slave with De-coupling, Dual feedback) for a dual stage hard disk drive system. Numerical simulations in both frequency and time domains show performance improvements of the dual stage hard disk drive system over the conventional single stage hard disk drive system.
