摘要
针对蠕动泵步进电机控制在升降速过程普遍存在速度波动大的问题,从硬件和软件两方面综合考虑,设计了一套控制系统。该系统以高性能ATmega8L单片机为控制器;软件编程采用硬件定时器中断和查询相结合的方法,在中断服务程序中根据直线升降速法对步进电机进行速度控制。实际运行表明,系统可靠,运行平稳,达到预期效果。
Designed a suit of control system which is used for peristaltic pump step motor, in hardware and software, which exists prob- lem of velocity fluctuation in the process of rise and fall speed. High performance MCU acts as controller; using the combined method of hardware timer interrupt and inquire to program, the controller control the speed of step motor based on linear rise-and-fall in the in- terrupt service routine. The used result shows that control system is stable, working stablely, achieving desired effect.
