硬盘驱动器的磁头定位控制的目的是将磁头迅速移动到所需的磁道上，并使其精确地保持在磁道上，以抵抗各种干扰和高频下的设备不确定性。作者将H/sup infinity / control应用于硬盘磁头的定位。为了获得良好的瞬态响应，他们采用了两个自由度的控制方案。实验结果表明，H/sup无穷大控制理论在硬盘控制系统中具有良好的控制性能，具有广阔的应用前景。<<ETX>>
The purpose of the head positioning control of hard disk drives is to move the magnetic head onto the desired track swiftly and to keep it on the track precisely against various disturbances and plant uncertainty at high frequency. The authors apply H/sup infinity / control to the head positioning of hard disk drives. To obtain a good transient response, they adopt the two-degree of freedom control scheme. The experimental results show a favorable control performance and indicate a very promising future for the application of the H/sup infinity / control theory to hard disk control systems.<<ETX>>
