查询词典 constant

Constant Angular Velocity mode and Constant Linear Velocity mode are integrated to build a single spindle motor control module to incorporate with long-seek servo. CAV mode and CLV mode are performed to show its feasibility. The experiment results showed that the pick-up-head can perform arbitrarily track-jump command, quite well.

此外，在主轴马达伺服部分，提出以跨轨旗标讯号来决定使用『碰-碰』控制法则让主轴马达转速变化的执行时间，也将主轴马达伺服中的等角速度控制模组与等线速度控制模组整合成功，形成单一的主轴马达控制模组，使与长寻轨伺服结合而更易於操作，让不论内、外寻轨的任意跨轨命令皆可以达成定线速度或是等角速度的控制目标。
