Adaptive Robust Controller Design For Dual-StaeeH ardD isk Drives

In this papcr, adaptive robust controllers :rre proposed lbr dual-stage hard disk drives. An Improved Desired Conrpcnsation ARC (lDCAll,C) schemc is proposed in this puper for both actuators of the systcm, in which the traditionnl ARC is powered by a dynamic adaptive term. Moreover, a simulation study of these controllers are presented, in which thc controllers designed based on simple models for the subsystem are implemented on a more comprehensive, experimentally verified models of the systern. Simulation result verilies the efltctiveness of the IDCrRC method in providing the rcquired trrcking, in prescnce of unstructured uncertainty lbr thc nrodels
