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
