Fuzzy Supertwisting Dynamic Surface Control for MIMO Strict-Feedback Nonlinear Dynamic Systems With Supertwisting Nonlinear Disturbance Observer and a New Partial Tracking Error Constraint

This paper proposes a hybrid fuzzy dynamic surface control (DSC) method combined with a supertwisting control (STC) method and a supertwisting nonlinear disturbance observer (STO) for multi-input multi-output nonlinear strict-feedback systems is proposed, in addition to a new partial tracking error constraining method. For the design of the stabilizing controls of the DSC, the virtual tracking errors in recursive procedures were transformed into...
