This note concerns the paper "On the controllability of a coupled system of two Kortewegde Vries equations" by Micu et al. . They study a nonlinear coupled system of two Kortewegde Vries equations and prove that the system is controllable by using four boundary controls. Here, we prove that in some cases it is possible to get the controllablity of the system by using only two controls. This can be done depending on both the spatial domain and the control time. © 2011 World Scientific Publishing Company.
