基于单片机的蠕动泵控制系统设计

摘要

It introduced a system of two phase stepping motor subdivision control peristaltic pump . MCU is the for the main control chip for the system . The subdivision control implement through the AVR producing sine wave signal pulse width modulation （PWM）. Pulse width modulation （PWM） is using the current tracking type SPWMscheme. The designed to increase the stability and the measurement precision of the stepping motor control. The whole system is with low cost and good real-time.%介绍了一种两相步进电机细分控制蠕动泵系统。单片机作为主控芯片，细分控制通过单片机产生正弦波信号进行脉宽调制（PWM）实现，脉宽调制（PWM）采用电流跟踪型SPWM方案。该设计提高了步进电机控制蠕动泵的稳定性及测量精度，整个系统成本低廉，实时性好。
