PARAMETER IDENTIFICATION OF STATIC AND DYNAMIC NONLINEAR SYSTEMS WITH SATURATIONS

Jozef Vörös

   The paper deals with the parameter identification of static and dynamic Hammerstein-type) systems having multisegment piecewise-linear characteristics with saturations. A new form of static multisegment nonlinearity representation with imposed internal variables allows an iterative estimation of nonlinearity parameters using measured input and output data. To demonstrate the feasibility of the identification method, more illustrative examples are included.
