| 摘 要： | 针对电液伺服闭环控制过程中,设定信号不断发生变化,电液阀门位置定位精确度较低的难题.采用AT-mega16L作为核心控制器,并配有高精度A/D、D/A转换器,通过对阀门开度控制信号和位置反馈信号进行采集、转换、计算和比较,发出控制信号决定并执行换向阀的换向、交流伺服电动机的起停运转,推动液压缸推杆的伸缩,进而对阀门转角大小、开度百分比进行精确定位.

| Abstract: | In the process of electro-hydraulic servo closed loop control,set signals are constantly changing and electro-hydraulic valve location accuracy is low.Through the acqusitiion,transformation,calculation and comparison of signals to control valve opening and position feedback signals,the system with ATmega16L as the core controller,equipped with high-precision A/D and D/A converters,sends a control signal to determine and perform the reversing of reversing valve and the operation of AC servomotor,promote the stretching of hydraulic cylinder rod,and thus realizes the precise position of the valve angle size and the opening percentage. |
