在实现高频高压型电子辐照加速器控制系统的分布式控制(Distributed Control System,DCS)的基础上,设计了一个以可编程逻辑控制器(Programmable Logic Controller,PLC)为控制核心,以小脑模型神经网络与PID(Cerebellar Model Articulation Controller and Proportional-Integral-Derivative,CMAC-PID)为主要控制算法的束流路径自动校正系统。实验表明:CMAC-PID控制器的调节速率和稳定度相比常规PID控制器均有较大提升,保证加速器在束流路径发生偏转时能快速稳定地将束流自动校正到芯管中间位置。
Based on the distributed control system (DCS) of the control system of high frequency and high voltage electron radiation accelerator, a programmable logic controller (PLC) is designed as the control core, Neural Network and PID (Cerebellar Model Articulation Controller and Proportional-Integral-Derivative, CMAC-PID) as the main control algorithm beam path automatic calibration system. The experimental results show that the adjustment speed and stability of CMAC-PID controller are greatly improved compared with the conventional PID controller, which ensures that the accelerator can automatically and quickly correct the beam current to the center of the core tube when the beam path deflects.
