چکیده :

In this paper, we present a new 1-D identification method for the identification of 2-D and singular 2-D systems. The previously introduced 1-D equivalent for 2-D systems which is called the Wave Advanced Model (WAM) suffers from a serious computational disadvantage. In WAM, the system matrices are rectangular and therefore the extensive 1-D literature which exists for systems with regular form square matrices cannot be applied to WAM. Furthermore, since WAM is a structure varying model, it is impossible to define an input-output difference equation for it and therefore the identification problem becomes even more complex. To overcome this complexity, here we present a method that allows us to define a 1-D input-output difference equation for Singular WAM (SWAM) and use it to solve the 2-D system identification problem using 1-D methods. In order to show the computational advantages of this method, a numerical example is also studied.
