摘要
对不相关噪声的多维时变系统,在相当一般的非持续激励条件下,建立了最小二乘算法的收敛速度,并通过引入衰减激励控制,在可辨识条件下,获得了该非持续激励条件.
Under the more general non-persistent excitation condition convergence rate of least squares algorithm for multidimensional time-varying systems with uncorrelated noise is established. By introducing attenuating excitation control the non-persistent excitation condition is obtained under identifying condition.
