This paper proposes a neural model for hysteresis. A method of continuous transformation is used to construct an elementary hysteresis model (EHM), which implements a one-to-one mapping between the input space and the output space of the hysteresis. The output of the EHM is used as one of the input signals of the neural network (NN) to approximate the behavior of hysteresis. A parabolic factor is introduced to improve the modeling performance for the major and minor loops of the hysteresis

A neural network based adaptive control scheme for systems with unknown hysteresis is proposed. In this scheme, an adaptive controller based on the proposed neural model is presented for a class of single-input nonlinear systems preceded by unknown hysteresis non-linearity. In order to handle the case where the output of hysteresis is immeasurable, the neural network model is utilized to estimate the influence of hysteresis. Based on the model-based estimation, the controller can compensate for hysteresis effect on the performance of the system.

A radial basis function network (RBFN) based adaptive H/sup /spl infin// control scheme for nonlinear systems with unknown hysteresis nonlinearity is developed. This scheme applies the method of pseudo-control to the design of the control strategy for the systems with hysteresis that cannot be measured directly. For the uncertainty of unknown hysteresis, the H/sup /spl infin// optimal control technique based on RBF neural network is utilized. Therefore, the tracking error of the system is suppressed to a prescribed small region. Finally, the effectiveness of the proposed control scheme is illustrated through simulation.
