摘要
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。
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.
