Aerodynamic Design via Control Theory [PDF]
Journal of Scientific Computing, 1988 The purpose of this paper is to propose that there are benefits in regarding the design problem as a control problem in which the control is the shape of the boundary. A variety of alternative formulations of the design problem can then be treated systematically by using the mathematical theory for control of systems governed by partial differential ...
