The problem of stabilizing a class of nonlinear plants via observer-based controllers is addressed. Quadratic Lyapunov functions are used to determine the existence of such controllers. Sufficient conditions for their existence are given in terms of Linear Matrix Inequalities, thus providing effective means to determine if these controllers exist.
