A Study of the Optimization of Magnet Power Supply Control Strategy for SC-200 Proton Accelerator Beam Transport Line

With the development of medical oncology, especially radiotherapy, proton therapy has emerged as a more effective and less damaging alternative to traditional treatment option. The necessity for higher precision and more rapid response times from the power supplies of proton accelerator beam transport lines increases with the extent and detail of the applications in question. In this paper, the transfer function of the SC-200 internal bunching fluid magnet power supply is derived and constructed on the basis of a number of fundamental principles. The LADRC feedback control algorithm was implemented, and the control parameters and outcomes were evaluated in comparison with those of the PID control algorithm, which is a standard technique employed in engineering applications. Practice has shown that The LADRC algorithm has been demonstrated to exhibit robust anti-interference capabilities, high processing speed, and stability. Consequently, the model is capable of identifying the optimal parameter settings for the construction of an accelerator beam transport line power supply.
