RMP(Resonant Magnetic Perturbation,共振磁场扰动)是托卡马克中用于磁流体力学不稳定性主动控制的基本手段之一,被广泛的应用于国际上各大主流装置。为了在EAST(Experimental Advanced Superconducting Tokamak)装置上开展相关的物理实验,在真空室内部设计制造安装了一套多功能的磁扰动线圈,在EAST PCS(Plasma Control System)上利用PID控制方法开发了RMP线圈电流控制算法,算法实现了对RMP线圈电流的开环与闭环控制。利用EAST PCS集成的simserver工具对算法进行了模拟运行测试,验证了算法的正确性。RMP线圈电流控制算法在2014年的EAST实验中得到了使用,实现了对RMP线圈电流的有效控制,为进一步的等离子物理研究奠定了基础。
Resonant Magnetic Perturbation (RMP) is one of the basic methods used in tokamak for the active control of magnetohydrodynamic instability. It is widely used in various mainstream devices in the world. In order to carry out the related physical experiments on the EAST (Experimental Advanced Superconducting Tokamak) device, a multifunctional magnetic disturbance coil was designed and manufactured inside the vacuum chamber, and the RMP was developed by PID control method on the EAST PCS (Plasma Control System) Coil current control algorithm, the algorithm realized on the RMP coil current open-loop and closed-loop control. The simulation run test of the algorithm is carried out by using the simserver tool integrated by EAST PCS, which verifies the correctness of the algorithm. The RMP coil current control algorithm was used in the 2014 EAST experiment, which realized the effective control of the RMP coil current, which laid the foundation for further plasma physics research.
