For a large class of nonlinear control systems, the main drawback of a semiglobal stabilizing output feedback controllers ${\left({𝒰}_R\right)}_{R>0}$ with increasing regions of attraction ${\left({\Omega }_R\right)}_{R>0}$ is that, when the region of attraction ${\Omega }_R$ is large, the convergence of solutions of the closed-loop system to the origin becomes slow. To improve the performance of a semiglobal controller, we look for a new feedback control law that preserves the semiglobal stability of the nonlinear system under consideration and that is equal to some...
