Robust Stability of Nonlinear System with Modified Prandtl-Ishlinskii Hysteresis Model

摘要：

In this paper,robust stability of nonlinear system with modified Prandtl-Ishlinskii (PI) hysteresis model is studied.In general,PI hysteresis model is the weighted superposition of play or stop operators.The slopes of the operators are same and equal to one.However,in fact,the slopes are not the same in practice.In order to make hysteresis model closer to the real hysteretic behavior,a modified PI hysteresis model with unknown slopes is concerned.With the proposed hysteresis model,the BIBO stability of the nonlinear system is achieved by a new condition based on robust right coprime factorization.A numerical example is presented to validate the effectiveness of the proposed robust condition.
