| 摘 要： | 对于时变参数的最小二乘估计问题，提出基于正交变换的限定记忆法，克服了传统方法因求解法方程而造成的病态加剧，且在不增加运算量的情况下，节省了存贮空间，改善了收敛性。

| Abstract: | An on-line least squares identification method is proposed for parameter estimation of time-varying systems by introducing a rectangular window to cancel the old measurement. The method is developed based on orthogonal transformation so as to avoid worsening the ill-condition. In addition, the method has the benefits of fewer arithmetic operations, less storage requirement and better convergence property compared with the traditional methods. |

| Keywords: | timevariable parameter estimation orthogonal transformation memory limited system parameter estimation. |
