Global regulation of a class of uncertain nonlinear systems using output feedback

In this paper we address the problem of global regulation by output feedback for a class of uncertain nonlinear systems dominated by a linearly growing triangular system. The growth rate of the nonlinearities is not known a priori, and therefore the problem is unsolvable by any existing results on this subject. By extending the output feedback domination design introduced in [15] to the time-varying case, we explicitly construct a linear time-varying output feedback control law which globally regulates the states of the systems without knowing the growth rate.
