根据硬磁盘驱动器磁头驱动机构的状态空间模型,运用极点配置技术和最优控制技术,分别设计了磁头定位系统在寻道模式和定道模式下的数字伺服控制器,以满足磁头定位系统寻道时间、定道精度等的性能要求,同时充分考虑了功牦限制、寻道残余振荡等影响。仿真结果表明其具有较好的控制性能。 According to the state space model of the head drive mechanism of hard disk drive, using the pole placement technology and the optimal control technology, the digital servo controller of the head positioning system in the seek mode and the fixed path mode are respectively designed to meet the seek time of the head positioning system , Path accuracy and other performance requirements, taking full account of the power yak limit, seek residual oscillation and other effects. Simulation results show that it has better control performance.
