Abstract: This paper deals with the structural and parametric identification of multivariable systems. A new recursive least squares algorithm to search for system structural parameterrs using the solution of undetermined linear equations with symmetric coefficients, and a criterion to test the system structure using the signs of coefficients of the system characteristic equation are developed. A simulated example is given.This recursive algorithm is also applicable to various modified least squares methods, such as the extended least squares method etc..
