In this paper, an indirect adaptive fuzzy control scheme is presented for a class of multi-input and multi-output (MIMO) nonlinear systems whose dynamics are poorly understood. Within this scheme, fuzzy systems are employed to approximate the plant's unknown dynamics. In order to overcome the controller singularity problem, the estimated gain matrix is(More)
In this paper, an indirect adaptive fuzzy control scheme is developed for a class of uncertain multi-input multi-output (MIMO) nonlinear systems with nonsymmetric control gain matrix. The nonsymmetric control gain matrix is expressed as the sum of a symmetric matrix and a skew symmetric matrix, and the symmetric matrix as well as the skew symmetric matrix(More)
In this paper, the fuzzy adaptive output feedback control strategy is investigated for uncertain multi-input and multi-output(MIMO) nonlinear systems with the external disturbances and unknown control direction. A state observer is constructed to estimate the unmeasured state, and an output feedback controller is developed by adaptive fuzzy control(More)
This paper addresses an adaptive fuzzy path following control scheme of a mobile robot with uncertainty of its center of mass. A fuzzy system is used to approximate the uncertainty function of the controller, the parameters in fuzzy system are adjusted by the tracking error. The approximation error can be efficiently counteracted by employing robust(More)
