Parameter identification of discontinuous Hammerstein systems. (English) Zbl 0886.93013

The paper deals with the problem of parameter identification of Hammerstein systems (cascade connections of static nonlinearity and linear dynamics) with a nonlinear static block having a discontinuous asymmetric and piecewise-linear characteristic. The approach is based on a decomposition technique, the so-called key-term separation principle, which provides nonlinear models in a special form, linear in the model parameters. The corresponding parameter estimation algorithm is presented and some examples, illustrating feasibility of the method, are given.
