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且不可或缺的存储介质。该存储介质已广泛应用于笔记本电脑、移动音频播放器、汽车导航、安全和通信系统等各种应用中。磁盘驱动器行业当前的目标是打破每平方英寸 1 太比特的存储密度障碍，这对传统单级磁盘驱动器伺服系统提出了严格的性能规范。为了应对这一挑战，人们提出了几种双级驱动方案。然而，所有这些建议都导致了多变量伺服系统，传统的标量设计技术不足以充分发挥该系统的潜力。因此，必须为双级多传感系统提出合适的设计方法，以明确和系统的方式追求最佳、鲁棒的性能。本提案就是对这一需求的回应。
