摘要

In order to improve the accuracy of the servo control system,based on the comprehensive consideration of the advantages and disadvantages of the traditional algorithm,a servo turntable control system based on single neuron PI was designed and accomplished.The system used SICK absolute multi loop encoder as the turntable displacement detection tool to form a closed-loop control system,in which the position loop used a single neuron PI algorithm to replace the traditional PI algorithm.Using FPGA programmable logic controller to realize the above algorithm;experimental platform servo control system.The experimental results showed that the precision of the rotating platform and the stability of the rotating speed could improve effectively.%为了提高伺服控制系统的精度,在综合考虑传统算法优缺点的基础上,设计并实现了一种基于单神经元PI的伺服转台控制系统.该系统采用SICK绝对式多圈编码器作为转台转动位置的检测工具,并把转台的位置输入到系统中形成闭环控制;其中位置环采用了单神经元PI算法取代传统的PI算法,并采用可编程逻辑控制器(FPGA)实现了上述算法;搭建了伺服控制系统的试验平台.试验结果表明,该转台的置位精度及转速的平稳性得到了有效提高.
