Adaptive Stabilization for a Class of Stochastic Nonlinear Systems with Prandtl‐Ishlinskii Hysteresis

This paper deals with a class of stochastic nonlinear systems with unknown hysteresis. A stochastic Lyapunov method is applied for systems in strict‐feedback form driven by unknown Prandtl‐Ishlinskii hysteresis and Wiener noises of unknown covariance. An adaptive controller is obtained which guarantees the global asymptotic stabilization in probability. Simulation results are provided to illustrate the effectiveness of the proposed approach.
