摘　　要：针对集成化储能与姿态控制系统中飞轮速度测量要求范围宽、精度高的特点,从误差分析的角度提出了一种速度测量方法。该方法在低速阶段测量多个完整飞轮转速脉冲信号所用时间,跨越转速分界点进入高速阶段后,测量一定时间内飞轮转速脉冲信号个数。为了验证该测量方法的可行性,文中以Agilent公司生产的高精度信号发生器及信号计数器为基准对该系统进行了速度测量实验,并对实验结果进行了分析。结果表明,该系统具有测速精度高,测量范围宽的优点,完全能够满足集成化飞轮储能与姿态控制系统测速精度的要求。To accomplish the wide range and high precision speed measurement in the attitude control and energy storage flywheel application, a new measurement method was put forward based on the analysis of the errors. In the low speed region, the time of several integrated flywheel speed pulse signal was measured. While the speed exceeds a certain threshold speed, the pulse number in a certain time was counted. For proving the feasibility of this method, the speed measurement experiment was done by using high precision arbitrary waveform generator and universal counter produced by Agilent Company, and the experiment results showed that the suggested speed measurement method can meet the demand of the integrated flywheel energy storage and attitude control system with the advantages of high precision and wide range.
