递推最小二乘法是参数辨识中最常用的方法A 但容易产生参数爆发现象,文推导了一种更稳定的辨识方法用递推阻尼最小二乘进行系统辨识-Recursive least squares method is commonly used in the parameter identification method A but easy to produce A burst of parameter phenomenon, wen A more stable identification method was deduced using recursive damped least squares identification system
