中文摘要	稳定回路是平台罗经及惯导系统的重要组成部分,其状态随工作时间的积累而逐渐改变。为了解决稳定回路缺乏有效在线监测手段的问题,采用基于最小方差控制的性能评估方法用于对稳定回路性能进行评估。以方位稳定回路为例,运用Diopphantine恒等式和FCOR(filtering correlation)算法,给出了稳定回路性能指标的计算方法。结果表明,该方法定义的性能指标显著下降时,稳定回路可能存在故障。同时,用自相关系数图法监测稳定回路是否振荡以及计算稳定回路的幅值和相角裕度的变化等方法,证明了该方法的有效性。; A stabilized loop performance assessment method based on minimum variance control(MVC) was developed to counter the decrease in precision and stability of stabilized gyrocompass and inertial navigation systems due to performance degradation of the stabilized loop with time.A performance criterion was developed using the Diopphantine identity and the filtering correlation(FCOR) algorithm for an azimuth stabilized loop as an example.Simulations show a definite relationship between a performance index and the loop status,with an obvious decrease in the index indicating faults in the loop.The method is validated by monitoring loop oscillations using the autocorrelation coefficient graph method and computing the changes in gain and phase margins of the azimuth stabilized loop.
