for linear control systems x_dot=Ax+Bu the reachability set can be calculated using the Image of the controllability matrix, i.e
R=([B AB A^2B,....,]) and reachability set=Im(R)
when rank(R)=n, and we do not have any control constraint the reachibilaty set of linear system is R^n (n is the dimension of states)
if we have a non-linear affine-control system
x_dot=f(x)+g(x)*u
R can be calculated using Lie algebra
R=[g1,g2,[f,g1],[f,g2],...]
my question is, in this case reachability set is again Im(R)?
and if reachability set=Im(R), how can we compute the rachability set, because here R will be a matrix with function arrays (function of states)

Dear Ali
May be interested to linearze the system and use the technique linear systems in finite and for infinite use the approach of semi-group in distributed parameter systems
Best regards
