利用辅助变量辨识方法,推导出多输入单输出系统的辅助变量递推最小二乘算法,并与辅助模型递推最小二乘法进行了计算量和辨识精度比较。
An instrumental variable based recursive least squares(IV-RLS)algorithm is derived for multiple input single output systems. The computational efficiency and identification accuracy of the IV-RLS algorithm and the auxiliary model based recursive least squares algorithm is compared.
