Abstract
A method for identification of dynamic characteristic quantities in a linear system having an electronic model, the electronic model having a complex signal flow with a complex residual a.sub.i =a'.sub.i +ja'.sub.i, and a complex inherent value b.sub.i =b'.sub.i +jb'.sub.i of the `i`th degree freedom describing model parameters a'.sub.i,a'.sub.i,b.sub.i ', and b'.sub.i for each degree of the system. The various signal flows are arranged parallel to one another for the various degrees of freedom, and are excited by the same signal `f` as the linear system. A difference e(n) determined at the time `n` between a model response `y` and a similar system response `d`, the system response having been time delayed by one unit of time, is used for adapting the model parameters for the system for the point in time (n+1), using variable step sized coefficients .alpha.'.sub.i (n),.alpha.'.sub.i (n),.beta.'.sub.i (n),&.beta.'.sub.i (n) for determining the accuracy of the adaptation to the system.
