DKSZ-Ⅲ电机实验装置的数字化改造

Digital Reform of DKSZ-Ⅲ Motor Experiment Equipment

根据"电力拖动自动控制系统"课程特点及要求,本文针对DKSZ-Ⅲ电机控制系统实验装置,在模拟控制直流双闭环单元电路基础上,开发了数字控制双闭环调速的实验挂箱。数字实验挂箱硬件由数字信号处理器TMS320LF2407及相应的外围接口电路组成,软件采用C语言与汇编语言混合编程,并包括一个ASR和ACR调节器。该挂箱实现了直流双闭环的数字控制,为本课程提供了数字实验平台。

According to the features and requirements of Power Drive Automatic Control System course, the digital control experiment box with double closed loops has been developed on base of the analog control module of DKSZ-Ⅲ motor control system experiment. The hardware of box is composed of digital signal processor TMS320LF2407 and corresponding peripheral circuit. The software of box is completed with C and assembly language. The design of ASR and ACR are finished with software. The box realizes digital control of direct current double closed loops, and provides the digital experiment platform for Power Drive Automatic Control System course.
