Abstract :
The authors present an indirect model-reference adaptive control scheme, which requires only output measurement, for SISO full-linearizable minimum-phase nonlinear systems. The nonlinearities are assumed to satisfy an output-matching condition, and only sector-type nonlinearities are allowed to multiply unknown parameters. The adaptive scheme consists of a certainty-equivalence control law and a prediction-error-type parameter estimator
