Abstract :
We consider a single-input single-output (SISO) nonlinear system which has a well defined normal form with asymptotically stable zero dynamics. Using only knowledge of the relative degree and the sign of the high-frequency gain, we design an output feedback integral controller which asymptotically regulates the output to a bounded time-varying reference signal with a constant limit. We give regional as well as semi-global results
