PARAMETER IDENTIFICATION OF HAMMERSTEIN SYSTEMS WITH ASYMMETRIC DEAD-ZONES

Jozef Vörös

   The paper deals with the parameter identification of Hammerstein systems having piecewise-linear nonlinearities with asymmetric dead-zones. A new form of nonlinearity representation provides a special form of Hammerstein model. Parameter estimation is carried out iteratively with measured input and output data records and estimated internal variables. To demonstrate the feasibility of the identification method, illustrative examples are included.
