摘要
介绍1种清花成卷机棉层厚度的控制方法。该系统采用单片机构成的模糊控制器,利用程序实现模糊算法和控制策略,与键盘、A/D与D/A转换器、位移传感器、电流变换频率调节装置及电机等组成实时数据采集和控制系统,替代原来的铁炮拨叉调速系统,对清花成卷机的给棉罗拉转速进行调节,使给棉罗拉在单位时间输出的棉量保持恒定。经过现场实际运行后表明,提高了系统的精度和动态特性,降低了棉卷不匀率,控制效果良好。
This paper discussed how to control the thickness of cotton lap with a fuzzy control system made up of single-chip processor. The system made use of program and applied fuzzy algorithm and control strategy. Its real-time data acquisition and control system consisted of keyboard, A/D or D/A converter, displacement sensor, motor and frequency governor. The old speed regulating system of the scutcher was replaced with the fuzzy control system which regulated the speed of cotton feeding roller of the scutcher in such a way that the cotton feeding in unit time was kept constant. The practical results show that it has improved the accuracy and dynamic response and reduced lap irregularity.
