This paper studies a controllability problem for blowup points of two classes of semilinear heat equations. Our goal to act controls on the systems we studied is to make the corresponding solutions blow up at given points. This differs with the controllability problem of equations with the property of blowup in the references, where the purpose of using controls is to prevent blowup by controls. We obtain the feedback controls for our controllability problem of blowup points.
