电磁型电磁永磁混合悬浮磁悬浮列车的悬浮系统是一个开环不稳定、强非线性时变系统。该文在分析了混合悬浮系统的工作原理的基础上,给出了一种电磁型磁悬浮系统直接自适应模糊控制器的设计方法。为了使控制算法在气隙变化的情况下能更快地收敛,提出了一种新的复合自适应算法。该算法能更加充分利用已有的先验知识,从而使系统的动态响应速度更快,跟踪误差更小。计算机仿真和实验结果都验证了理论分析的正确性。
Suspension system of electromagnetic electromagnetic permanent magnet hybrid suspension magnetic levitation vehicle is an open-loop unstable, strong nonlinear time-varying system. Based on the analysis of working principle of hybrid suspension system, a design method of direct adaptive fuzzy controller for electromagnetic magnetic suspension system is presented. In order to make the control algorithm converge more quickly when the air gap changes, a new compound adaptive algorithm is proposed. The algorithm can make full use of existing prior knowledge so that the dynamic response speed of the system is faster and the tracking error is smaller. Computer simulation and experimental results verify the correctness of the theoretical analysis.
