“…In the last decade, many contributions have addressed the design of stabilizing switching laws for switched systems both in continuous and discrete time (see for examples [1], [2], [3], [4] for dynamic programming approaches, [5], [6], [7] for variational approaches, and [8], [9], [10] for Lyapunov based approaches). This problem cannot be considered trivial even numerically [11], [7] and the goal to design closed loop control, based on the optimization of a criteria, is a challenging task.…”
