摘要

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。

Abstract

Background: Dynamitron

an electron irradiation accelerator of high-voltage

is used as a radiation source for industrial and agricultural production. The control system is an important component of dynamitron. Purpose: The aim is to improve the control system to meet the performance requirements of dynamitron for the stability. Methods: A distributed control system for the 1.5-MeV dynamitron is proposed to gain better performance. On this basis

an electron beam trajectory automatic correction method based on Cerebellar Model Articulation Controller and Proportional-Integral-Derivative (CMAC-PID) controller is designed to improve the function of electron beam extraction system. Results: The distributed control system can meet the control requirements of the accelerator. The stability of the CMAC-PID controller is better than that of conventional PID controller for the electron beam trajectory automatic correction system

and hence the CMAC-PID controller can provide better protection of dynamitron when electron beam deflection occurs. Conclusion: The distributed control system and the electron beam trajectory automatic correction method system can effectively improve the performance and reduce the failure probability of the accelerator

thereby enhancing the efficiency of the accelerator.Cited
