| 中文摘要 |
| 给出时变参数的一种快速跟踪最小二乘估计方法。该方法对测量数据同时引入指数加权因子和矩形窗，综合了渐消记忆法和限定记忆法的优点。利用抗病态的正交变换法求解估计值，以减小权固子和窗长度，提高了估计值的跟踪速度。 |
| 英文摘要 |
| A least squares method for the parameter estimation of quickly systems is proposed. The forgetting factor and the rectangular window are simultaneously introduced in the method so that the benefits of both methods are utilized. In order to solve the problem of ill-condition where the little forgetting factor and the window length are chosen to follow the tracks of varying parameter quickly, an orthogonal transformation method is used. |
