Existence and uniqueness of minimal realizations for a class of $$C^{\infty}$$ systems. (English) Zbl 0591.93013
This work considers the differential geometry approach for nonlinear control theory. In particular, the authors extend to the noncompact case some results due to H. J. Sussmann [see Math. Syst. Theory 10, 263- 284 (1977); J. Differ. Geom. 10, 151-166 (1975; Zbl 0342.58004); Bull. Am. Math. Soc. 80, 573-575 (1974; Zbl 0301.58002)] in the analytic and symmetric cases and to themselves [see Syst. Control Lett. 1, 395-398 (1982; Zbl 0497.93014)] in the compact case. For the nonlinear control theory point of view this enables to state the existence and uniqueness of minimal realizations for a class of $$C^{\infty}$$ completely controllable and weakly observable systems.
