| Abstract: | A new method to compute weighting matrices in the linear subspace identification is presented,this method is linear systems based on advantage of three algorithms among N4 SID,MOESP and MOESN4,the method MOESN4 is modified and promoted,the main aim to treat the given weighting matrices are used,which makes more choices to the weighting matrices,increases practical application of the presented algorithm. Finally,two kinds of certain different weighted average methods MOESN4 WAc and MOESN4 WAd are provided. |
