飞轮电池磁悬浮控制系统的仿真和实验研究

提出了一种用于飞轮电池的电磁和永磁混合磁悬浮轴承设计方案，其轴向位移由电磁铁主动控制，其余自由度由永磁铁以吸力方式给以约束，同时由永磁铁提供电磁控制的偏置磁场。对电磁力和永磁力进行了有限元计算和线性化，建立了磁悬浮控制系统的模型。对系统在不同的PID控制器参数下。受到阶跃扰动力的位移响应进行了仿真。采用上述磁悬浮方案和PID控制器，完成了一个单自由度磁悬浮实验，洲试了飞轮转子轴向脉冲力位移响应．实验结果证实上述磁悬浮方案和控制器能够实现飞轮转子的稳定悬浮。

Simulation and Experiment of Maglev Control System for Flywheel Battery

A hybrid magnetic bearing for the flywheel battery was proposed which incorporated both the electromagnetic control and permanent magnets, namely, the flywheel's axial freedom was actively controlled by electromagnet while the other DOFs were restricted by the permanent magnets in attractive mode, simultanoeusly, the permanent magnets also provided the bias flux for electromagnetic control. After the magnetic force was computed and linearized by Finite Element Analysis, the maglev system was modeled and then simulated in response to a impulse force under different PID controller parameters. Using the above maglev design and PID controller, an 1-DOF maglev experiment was successfully implemnted and the axial displacement response to a impulse force was tested. The experimental results show that the proposed maglev design and PID controller can make the flywheel rotor suspend stalbly.
