In this section, we look at the output measurement-feedback problem for a more general class of nonlinear systems. For this purpose, we consider the following class of nonlinear systems defined on a manifold containing the origin in coordinates x = (x1, …, xn):
where all the variables have their previous meanings, while is the state dynamics function, is the controlled output function and is the measurement output function. Moreover, the functions F (., ., .), Z(., .) and (., .) are smooth Cr, r ≥ 1 functions of their arguments, and the point x = 0 ...
