Simplified Dynamic Surface Control for Uncertain Nonlinear Systems
A novel fuzzy adaptive regulation approach is proposed for a class of output-feedback nonlinear systems based on dynamic surface control (DSC). The whole system is needed only one fuzzy approximator, and therefore only one approximator error and one unknown fuzzy parameter vector need to be tackled adaptively, so that the whole controller structure is more simpli ed than the existing result. It is proved that the proposed design approach is able to guarantee semi-global uniform ultimate boundedness (SGUUB) of all signals in the closed-loop system, with arbitrary small error by appropriately choosing design constants.
