In this paper, the problem of output tracking for single-inputlsingle-output nonlinear systems in the presence of mismatched uncertainty is studied. In our problem, the so-called matching condition in the literature is further relaxed, and a more general condition on the uncertainty is given. To att

β¦ Synopsis
The purpose of this paper is to compare di!erent features of two approaches to the problem of tracking-prescribed trajectories in a nonlinear system, and to propose a possible merger of these approaches in what is called here the problem of `Asymptotically Robust Perfect Trackinga. The latter is the problem of designing a feedforward/error-feedback control law achieving perfect tracking in case the initial conditions of the system/exosystem are known and compatible with perfect tracking, and asymptotic tracking in all other cases.
