单片机在光盘自动换盘机构中的应用

The application of monolithic computer to mechanism of automatic changing of compact disks

采用８０３１单片机控制光盘自动换盘机构位置系统，设计了数字脉宽调制器，数字调节器采用开关控制和ＰＩＤ控制，使系统具有较好的动态性能。

The 8031 monolithic computer is adopted in this paper to control the position system of mechanism of automatic changing of compact disks. The digital pulse- width modulator has been designed. It uses thecontrol of bang-bang and PID(proportionalintegral-differential controller), thus makes this system possess fairly good dynamic characteristics.
