In the first part, we revisit the proportional navigation feedback (PNF) approach, and we show that it can be appropriately recasted within the framework of time-varying homogeneity. As a first consequence, we recover all previously obtained results on PNF with simpler arguments. We then apply sliding mode-inspired feedbacks to achieve prescribed stabilization with uniformly bounded gains. However, all these feedbacks are robust to matched uncertainties only. In the second part, we provide another sliding mode-inspired feedback which not only stabilizes the pure chain of integrators in prescribed time but also exhibits some robustness in the presence of measurement noise and unmatched uncertainties.Show less >
