Adaptive Compensating Control Method for Dynamic Hysteresis Nonlinearity

A new compensating control method for a kind of typical dynamic hysteretic model is proposed.An ideal hysteretic model with approximate linear characteristics is transformed into an actual expected output model by multiplying a slope conversion factor.Using adaptive sliding mode control principle,hysteretic compensation control law is calculated in order to guarantee the actual hysteresis characteristics to reach the expected linear output.Simulation results showed the validity of the sliding mode compensating method for the hysteresis characteristics.
