Uncertainty and Performance of Adaptive Controllers forFunctionally Uncertain Output Feedback
We consider nonlinear systems in an output feedback form which are functionally known up to a L 2 measure of uncertainty. The control task is to drive the output of the system to some neighbourhood of the origin. A modiied L 2 measure of transient performance (penalising both state and control eeort) is given, and the performance of a class of model based adaptive controllers is studied. An upp...
متن کاملA dynamic output feedback controllers for mismatched uncertain variable structure systems
This paper proposes a dynamic output feedback controllers for variable structure systems. It is based on the concept of output feedback controllers, introduced by Z ak and Hui (IEEE Trans. Automat. Control AC-38 (1993) 1509) and Kwan (IEEE Trans. Automat. Control AC-41 (1996) 1691) for matched uncertain variable structure systems in which the state is unavailable and no estimated state is requi...
متن کاملUniversal Output-feedback Siso Controllers
It is proved in the paper that practically all known higher-order sliding controllers can be combined with recently developed 2-sliding-mode-based differentiators yielding universal output-feedback Single-Input-Single-Output (SISO) controllers. These controllers can be applied at least locally, whenever the system relative degree is known. The convergence is global, provided the system relative...
متن کاملPotentials of Evolving Linear Models in Tracking Control Design for Nonlinear Variable Structure Systems
Evolving models have found applications in many real world systems. In this paper, potentials of the Evolving Linear Models (ELMs) in tracking control design for nonlinear variable structure systems are introduced. At first, an ELM is introduced as a dynamic single input, single output (SISO) linear model whose parameters as well as dynamic orders of input and output signals can change through ...
متن کاملADAPTIVE FUZZY OUTPUT FEEDBACK TRACKING CONTROL FOR A CLASS OF NONLINEAR TIME-VARYING DELAY SYSTEMS WITH UNKNOWN BACKLASH-LIKE HYSTERESIS
This paper considers the problem of adaptive output feedback tracking control for a class of nonstrict-feedback nonlinear systems with unknown time-varying delays and unknown backlash-like hysteresis. Fuzzy logic systems are used to estimate the unknown nonlinear functions. Based on the Lyapunov–Krasovskii method, the control scheme is constructed by using the backstepping and adaptive techniqu...
