| Abstract: | A new estimation method is proposed for time varyig process to avoid the ill condition of least squares method. Based on the new method, the new recursive least squares algorithm is constructed. The new estimation method can ease the ill condition and improve the estimation accuracy without using the additional signals. Moreover, without additional computation, it is suitable for engineering practice very much. Both simulation results and practical operation show the new identification algorithm is effective. In this paper, the justification of this modified algorithm is proved. |
