该文研究了光盘机二级执行机构的多变量颇域特性;研究了道跟踪伺服系统构成的特点，给出了两种可能的结构设计。对两级之间位置可测的系统，给出了直接单变量控制的方法和系统结构，以及计算机仿真结果。
This paper studies the multivariable domain properties of the two-stage actuator of the optical disc drive. The characteristics of the tracking servo system are studied. Two possible structural designs are given. For the system with measurable position between the two levels, the method and system structure of direct univariate control and the results of computer simulation are given.
