First, the fuzzy logic systems are applied to estimate the boundary of the lumped uncertainties. Next, based on the Lyapunov stability theorem, a MRAFSMC law to solve the control problem is proposed. Moreover, the chattering around the sliding hyperplane in the sliding mode control (SMC) can be reduced by the proposed design approach. The proposed strategy not only possesses the advantages of SMC and adaptive fuzzy control, but also eliminates the disadvantage of traditional SMC. A numerical example is given to illustrate the feasibility of the proposed control strategy. Advisor Committee Chung-chun Kung - advisor
