PC机和单片机对机电传动系统的分级控制,其中PC机为上位机,单片机为伺服级计算机,上位机负责总体控制并及时向各伺服级计算机发送位置命令;伺服级计算机利用伪微分反馈控制算法对电机位置进行实时控制。同时,文中对计算机通讯和数据采集以及程序编制中出现的问题提出了解决办法。 PC and SCM control the grading of the electromechanical drive system. The PC is the upper computer and the single-chip computer is the servo-level computer. The upper computer controls the overall control and sends position commands to each servo-level computer in time. The servo-grade computer uses the pseudo-differential feedback control algorithm Real-time control of the motor position. At the same time, the paper presents some solutions to the problems in computer communication, data collection and programming.
