In
this paper, we study the state controllability and nodal
profilecontrollability for a scalar conservation law, with a nonlocal
velocity, that models a highly re-entrant manufacturing system as
encountered in semi-conductor production. We first prove a local state
controllability result, i.e., there exists a control that drives the
solution from any given initial data to any desired final data in a
certain time period, provided that the initial and final data are both
close to a given equilibrium. We also obtain a global state
controllability result for the same system, where there is no
limitation on the distance between the initial and final data. Finally,
we prove a nodal profile controllability result, i.e., there exists a
control under which the solution starts from any initial data reaches
exactly any given out-flux over a fixed time period.
