递推最小二乘算法能随着观测数据的更新逐次的估计出模型参数值，用新引入的数据对上一次估计的结果进行修正，从而递推地估计出下一个参数估计值。-The recursive least squares algorithm with successive estimation update observation data the model parameter values of an estimate of the results is modified by the introduction of new data, to recursively estimate the next parameter.
