Remarks on approximate controllability
Journal d'Analyse Mathématique, 1992The problem of exact and approximate controllability for the wave equation with boundary control is studied. It is introduced the duality method which allows the treatment of the original problem via variational inequalities. Many pertinent remarks are made and some open problems are formulated.

Controllability, Approximations and Stabilization
1989A wide variety of systems in e.g. engineering or biological applications can be described or modelled by control systems (or controlled differential equations) of the general form \(\dot x = F\left( {x,u} \right)\) where the state a; is a point on a smooth manifold, the control u takes values in a compact interval or another manifold and is integrable ...

Suboptimal control using Pade approximation techniques
IEEE Transactions on Automatic Control, 1980A method is given for the design of suboptimal controllers for single-input single-output systems using partial state feedback. This is based on the Pade approximation technique for model order reduction.
