The problem of guiding a system onto a terminal set from an unknown initial point was explored in an ASA study [1][2], where the authors developed an approach for linear control systems to construct a closed-loop control based on an open-loop treatment. For linear systems with discontinuous input matrices, ASA researchers carried out an asymptotic analysis enabling the construction of an attainability domain given that phase constraints can be fuzzy, reflecting the possibility of shock scenarios and a limited precision of real-life data respectively [3][4].

In addition, ASA work in this field used a probabilistic framework for modeling diffusion in networks to demonstrate how network diffusion can be externally manipulated by injecting time-varying input functions at individual nodes and by modifying the dominant diffusion modes [5].
