摘要: 本文提出了一种对噪声系统模型A(z-1)y(k)=B(z-1)u(k)+A(z-1)ε(k)LS估计的偏差补偿方法。仿真结果表明,以补偿后的参数估值作广义最小二乘法的初值,可以得到更好的结果。

Abstract: In this paper, a method for compensating the bias which results from the LS estimation of the model A(z-1)y(k) = B(z-1)u(k) + (z-1)e(k) is developed At the same time, simulation result shows that we can get a better result by using GLS technique with initial value which is the compensated estimate
