Identification of Nonlinear Cascade Systems with Time-Varying BacklashDOI: 10.2478/v10187-011-0014-2 Keywords: nonlinear systems, backlash, cascade systems, recursive identification, time-varying systems Abstract: Recursive identification of cascade systems with time-varying input backlash and linear dynamic system is presented. A new analytic form of backlash characteristic description is used, hence all the parameters in the cascade model equation are separated and their estimation is solved as a quasi-linear problem using the recursive least squares method with internal variable estimation. Simulation studies are included.
