Magnetic hard disk drives are widespread and indispensable storage media nowadays. The storage media has been widely used in various applications ranging from lap-top computers, mobile audio players, car navigation, to security and communication systems. A current goal of the magnetic disk drive industry is to break the 1 tera-bit per square inch storage density barrier, which imposes a stringent performance specification for the conventional single-stage disk drive servo. To meet the challenge, several dual-stage actuation schemes have been proposed. All these proposals, however, lead to a multivariable servo system for which conventional scalar design techniques become inadequate to fully exploit the potential of that system. Thus, it is imperative to come up with appropriate design methodologies for the dual-stage multi-sensing system, in which optimal, robust performance is pursued in an explicit and systematic way. This proposal is a response to this need.

磁性硬盘驱动器是当今广泛和不可缺少的存储介质。存储介质已广泛用于从膝上型计算机、移动的音频播放器、汽车导航到安全和通信系统的各种应用中。磁盘驱动器工业的当前目标是突破每平方英寸1兆兆比特的存储密度障碍，该障碍对传统的单级磁盘驱动器伺服施加了严格的性能规范。为了应对这一挑战，已经提出了几种双级驱动方案。然而，所有这些建议，导致多变量伺服系统，传统的标量设计技术变得不足以充分利用该系统的潜力。因此，必须提出适当的设计方法的双级多传感系统，其中最佳的，鲁棒的性能是追求在一个明确的和系统的方式。这项建议是对这一需要的回应。
