Allan_Variance
- allan 方差(阿伦方差)是David AIlan于1966年提出的,最初该方法是用于分析振荡器的相位和频率不稳定性,高稳定度振荡器的频率稳定度的时域表征目前均采用Allan方差。由于陀螺等惯性传感器本身也具有振荡器的特征,因此该方法随后被广泛应用于各种惯性传感器的随机误差辨识中。(Allan variance (Allen variance) was proposed by David Allan in 1966. Initially this method was used to anal
最小方差(间接)自校正控制算法
- 由于一般工业对象存在纯延时 ,当前的控制作用要滞后 个采样周期才能影响输出。因此,要使输出方差最小,就必须提前 步对输出量进行预测,然后根据所得的预测值来设计所需的控制律。这样,通过连续不断地预测和控制,就能保证稳态输出方差最小。由此可见,实现最小方差控制的关键在于输出预测。
