摘 要：In this paper,an approach based on backstepping techniques is proposed to design robust H ∞ tracking controller for a class of strict-feedback stochastic nonlinear systems with It?-*** approach employs backstepping techniques and combines Lyapunov theory with robust H ∞ disturbance attenuation performance to design H ∞ tracking *** difficulties are avoided for solving the Hamilton-Jacobi equations or the Hamilton-Jacobi inequalities as well as LMIs,which present in the existing papers,so that the controller can be designed more *** designed controller can guarantee that the output tracking error of the system is bounded in probability,at the same time,it can assure that all signals in the closed-loop system are bounded in probability,and there is the H ∞ disturbance attenuation performance for the external ***,the simulation results demonstrate the feasibility and validity of the proposed control scheme.
