摘要
为通过多极磁悬浮技术实现悬浮体在三维空间内任意位置的悬停,针对这一具有广阔前景的应用,建立磁悬浮动力学模型对多极磁悬浮技术的实现至关重要。对一种四极电磁铁磁悬浮装置进行了理论分析,建立了四极磁悬浮系统的状态空间线性方程,使用DRNN神经网络算法对系统进行了参数辨识,获得了四极磁悬浮的精确模型,为悬浮体在多极磁悬浮空间操控奠定了基础。
Multi-pole magnetic levitation technology to realize the hovering of the suspension at any position within the three-dimensional space has broad application prospects.The establishment of a magnetic levitation model is essential for the realization of multi-pole magnetic suspension technology.A quadrupole electromagnet magnetic levitation device is analyzed theoretically,and the state space linear equation of quadrupole magnetic levitation system is established.The parameters of the system are identified by DRNN neural network algorithm,and an accurate model of quadrupole magnetic levitation is obtained,which provides the foundation for the control of the suspension in the multi-pole magnetic levitation space.
