摘　　要：现有的磁悬浮地球仪系统主要通过调节电磁线圈的电流来控制悬浮体的位置,电磁控制的悬浮系统存在功耗大、能量的利用率不高等问题。对于一种主要承载力为永磁力、调节控制力为电磁力的混合磁悬浮地球仪结构,建立了其线性化动力学模型,并基于模型设计了零功率控制器以降低磁悬浮系统的功耗。仿真及实验结果表明:所设计的控制系统能有效克服电磁控制型磁悬浮地球仪能耗大的不足,起到节能的作用。The existing magnetic levitation globe system mainly controls the position of the levitation body by adjusting the current of the electromagnetic coil.The electromagnetically controlled levitation system has the problems of high power consumption and low energy utilization.For a hybrid magnetic levitation globe structure whose main bearing capacity is permanent magnetic force and the regulating and controlling force is electromagnetic force,a linear dynamic model of the hybrid magnetic levitation globe is established,and a zero-power controller is designed based on the model to reduce the power consumption of the magnetic levitation system.Simulation and experimental results show that the designed control system can effectively overcome the large energy consumption of electromagnetically controlled magnetic levitation globes,and play a role in energy saving.
