The self-servo track writing (SSTW) process for hard disk drives (HDDs) consists of axial (or time) and radial (or track) dimensions and is described by using a 2-D model. Within the 2-D system framework, the error propagation containment problem of the SSTW is formulated as a 2-D stabilization problem, and the position error minimization problem is formulated as a 2-D H control problem. The adopted...
Self-servo track writing (SSTW) process for hard disk drives (HDDs) is described by using a two-dimensional (2D) model, with which the error propagation containment problem of the SSTW is formulated as 2D stabilization problem, and the position error minimization problem is formulated as 2D H2 control problem. The adopted 2D controller is designed with easily implemented linear matrix inequality (LMI)...
