Differential equations and systems analysis. Undergraduate controls and/or signal processing course would satisfy this requirement. A graduate-level systems course is also helpful, but not necessary.

Mathematics of Computation, Vol. 57, No. 195 (Jul., 1991), pp. 123-151 (29 pages) We examine certain analytic and numerical aspects of optimal control problems for the stationary Navier-Stokes ...

In this paper, we study variational discretization for the constrained optimal control problem governed by convection dominated diffusion equations, where the state ...
