A bang-bang result for point control

Pages 261-269 | Received 23 Mar 1981, Published online: 10 May 2007
 

Abstract

In this note we consider the control of a pseudo-parabolic or parabolic problem at a point a in subject to constraints. We obtain a bang-bang property for an optimal control that depends on whether the components of a are irrational. We also show that such a result does not hold for the parabolic case p = 2 or 3.
