摘要

提出了一种光盘驱动器复合驱动器的模糊控制方法。解决了与复合执行机构控制相关的许多问题。粗致动器通常具有与精细致动器非常不同的分辨率,精细致动器受其行程的限制。模糊控制逻辑为实现这些规范提供了一种简单的方法。比较了不同配置模糊控制器的应用结果。然后提出了一种混合控制算法。结果表明,采用模糊控制算法可以将航迹接近和航迹跟踪两阶段控制的常用方法结合起来。

Servo controller design for an optical disk drive using fuzzy control algorithm
The fuzzy control of an optical disk drive compound actuator is presented. Many problems associated with the compound actuator control are addressed. The coarse actuator generally has a very different resolution from that of the fine, and the fine actuator is limited by its stroke. The fuzzy control logic provides an easy way for implementing these specifications. Results for fuzzy controller applications with different configurations are compared. A hybrid control algorithm is then proposed. It was shown that the common approach of using two stage control for track accessing and track following can be combined by using the fuzzy control algorithm.<>
