Research Of Subspace System Identification And Expioitation Of Its Software Kit

In the paper a quite new system identification method--subspace systemidentification method is introduced. Firstly, the forming background and theapply range of the method and the advantage comparing with the traditionalidentifying methods are introduced. Secondly, I explain detailedly the algebrafoundation of the subspace system identification method --subspace projectiontheorem.Thirdly, several basic subspace system identification methods arebrought forward, through comparing the common characteristics of the severalmethods, unifying theorem of the subspace system identification is broughtforward. Finally, through the emulate of the single-input single-output system andmulti-input multi-output system, the validity of the subspace systemidentification method is showed.
