Abstract :
A novel modeling of nonlinear plants with hysteresis is proposed. The hysteresis nonlinearity is described by a modified Prandtl-Ishlinskii hysteresis model which is the weighted superposition of non-symmetric play operator. The proposed hysteresis model also facilitates the utilization of robust right coprime factorization. Simulation result is presented to show the feasibility of the proposed hysteresis model.
