摘　　要：首先提出由于卫星在轨可靠性的要求,耐辐射FPGA成为航天工业应用的趋势。针对此需求,设计出一种基于FPGA实现的傅里叶光谱仪动镜电机控制算法,给出了数字控制器的硬件架构和状态机的实现方法。Modelsim中的代码仿真说明了算法的有效性。经系统运行验证,动镜实际运动位置跟踪期望位置效果好,匀速区速度波动均方根值可达1.4%,为星载傅里叶光谱仪动镜电机数字控制器的实现提供了一种技术途径。The use of FPGA is a trend of space industry because of the demand for high reliability of satellite in outer space. A method of moving mirror motor ＇s digital controller for Fourier transform spectrometer implemented by using FPGA was put forward. The frame of digital controller and implementation of state machine was given. Code simulation illuminated the validity of the design. Experiments show that the position of moving mirror tracks the expected position, and the speed vibration in the value of RMS is 1.4%. The new control technology of moving mirror motor＇s digital controller is applicable to Fourier transform spectrometer in spaee.
