位置伺服系统的硬件设计

Hardware design for a positioning servosystem

本文阐述了位置伺服系统的结构组成及硬件实现，特别是对以往位置反馈回路中的四倍频器和脉冲计数电路做了改进，最后实验结果表明，该系统设计合理且能有效避免电机起始的跳动。

The hardware construction of a positioning servosystem is described.Especially,the improvement of a previous position detector including its frequency multiplier and counting circuit is discussed in detail.The reasonableness of this design and the avoidance of the start jolt of a motor have been proved by experiments.
