摘要: The state space approach, principally introduced by Bellman † (cf. [1]) and Kalman, deeply changed the outlook on automatic control from 50’s onwards. Then, as geometrical methods appeared, 70’s yielded a sound knowlegde of autonomous linear systems Wonham [66]) while, with introduction differential geometry thanks to Hermann [30] Lobry [44] in particular, nonlinear actually emerged (*).
