摘要
为了量化分析不同初始平衡磁剪切对共振磁扰动诱发的双撕裂模的影响,提出基于非线性多参数约束的不同初始平衡磁剪切对共振磁扰动诱发的双撕裂模控制模型。构建磁剪切对共振磁扰动诱发的控制约束参量模型,采用极低频外电场持续扰动方法进行不同初始平衡磁剪切对共振磁扰动建模,结合容积卡尔曼滤波方法进行共振磁扰动诱发的抑制处理,提取不同初始平衡磁剪切对共振磁扰动诱发的量化特征量。采用随机量化博弈和定量递归分析方法进行共振磁扰动诱发的双撕裂模自适应控制,分析共振磁扰动诱发对双撕裂模的稳定性控制因素,结合不同的刺激参数进行自适应参数估计和寻优,实现不同初始平衡磁剪切对共振磁扰动诱发的双撕裂模的定量递归分析。仿真结果表明,采用该方法进行共振磁扰动诱发双撕裂模的稳定性控制能力较好,收敛性较强,提高了双撕裂模的磁鲁棒性。
In order to quantitatively analyze the effect of different initial equilibrium magnetic shear on the double tearing mode induced by resonance magnetic disturbance,a double tearing mode control model with different initial equilibrium magnetic shear induced by resonant magnetic disturbance based on nonlinear multi-parameter constraints is proposed.The control constraint parameter model induced by magnetic shear induced by resonance magnetic disturbance is constructed,and the resonant magnetic disturbance model with different initial equilibrium magnetic shear is established by using the method of very low frequency external electric field continuous disturbance.The volume Kalman filtering method is used to suppress the magnetic disturbance induced by resonance magnetic disturbance,and the quantitative characteristics of different initial equilibrium magnetic shear induced by the resonance magnetic disturbance are extracted.The adaptive control of double tearing mode induced by resonance magnetic disturbance is carried out by means of stochastic quantitative game and quantitative recursive analysis,and the factors controlling the stability of double tearing mode induced by resonance magneticdisturbance are analyzed.Combined with different stimulus parameters,adaptive parameter estimation and optimization are carried out,and quantitative recursive analysis of double tearing modes induced by resonance magnetic disturbance with different initial equilibrium magnetic shear is realized.The simulation results show that the proposed method has good stability control ability and strong convergence and improves the magnetic robustness of the double tearing mode induced by resonance magnetic disturbance.
