Abstract :
An adaptive inverse control approach is put forward to control a kind of typical nonlinear system with hysteresis characteristic. An inverse of the hysteresis operator is proposed and the inverse nonlinear model is built. Then the structure of filtered-ε LMS algorithm is simplified and a new adaptive inverse control system is built to reduce the nonlinearity and achieve accurate tracking control. Simulation results illustrate the proposed scheme´s effectiveness.
