| 摘 要： | 针对电磁振动料斗固有频率易于漂移,从而使其偏离共振区,造成供料性能下降的问题,设计了一种数字调频振动料斗控制器;该控制器采用PIC16F876单片机作核心元件进行开发,通过压电片反馈的信号分析振幅和频率变化,运用数字调频脉冲对固有频率进行跟随,使电磁振动料斗稳定在共振区,并通过调节电压对振幅进行调节,使料斗达到最佳供料状态;该控制器已经在轴承保持架供料系统得到应用,实践证明所设计的控制器使供料系统的性能得到较大提高。

| Abstract: | To solve the problem that the natural frequency of the electromagnetic vibration feeder often drifts and it leads to the deline of feeding material performance,a digital frequency adjustment vibration feed controller is designed.The controller uses PIC16F876 microcontroller as the core component.It analyses the change of amplitude and frequency through the feedback signal of the piezoelectric film and outputs the digital pulse to follow the natural frequency,so that the electromagnetic feeder keep on in the... |
