摘　　要：设计了一个以开关磁阻电动机(SRM)为驱动电动机的飞轮储能系统。首先,将有限元法和神经网络技术相结合,在Matlab中建立了整个系统的仿真模型,对系统的充放电过程进行了仿真分析;然后,以数字信号处理器和复杂可编程逻辑器件为控制核心,搭建了系统的硬件实验平台,并进行了初步的性能测试;最后,将系统应用于小型航天器姿态调整中,依据角动量守恒定律,通过两个飞轮储能系统的转速差达到姿控的目的。同时建立了航天器的单轴简化仿真模型以及三维动画模型,对姿控过程进行了仿真验证。A flywheel energy storage system （FESS） driven by switched reluctance machine （SRM） is designed. The model of the whole FESS is built firstly in Matlab software by combining the finite element method （FEM） and neural network （NN）, and the charge-discharge process is simulated and analyzed. Taking DSP and CPLD as key control components, the hardware experimen- tal platform of the system is then implemented and performance tests are carried out preliminarily. Furthermore, the system is applied to the attitude control of small spacecraft. According to principle of conservation of angular momentum, the attitude can be adjusted by the speed difference between two FESSs. In addition, the simplified uniaxial model and 3D animation model are built for the spacecraft, and the process of attitude control is verified by simulation.
