Approximate Controllability of Delayed Semilinear Control Systems

We deal with the approximate controllability of control systems governed by delayed semilinear differential equations ẏ(t) =Ay(t) +A1y(t−∆) +F(t, y(t), yt) + (Bu)(t). Various sufficient conditions for approximate controllability have been obtained; these results usually require some complicated and limited assumptions. Results in this paper provide sufficient conditions for the approximate cont...

Exact Controllability of Semilinear Systems with Impulses

The purpose of this paper is to investigate the controllability of the impulsive semilinear system x′(t) = A(t)x(t) + f(t, x(t)) + B(t)u(t), t ≥ t0, t 6= tk, x(t+k ) = x(t − k ) + Ik(x(t − k )), k = 1, 2, 3, . . . . By making use of Schaefer’s fixed point theorem we obtain some results under which the system is completely controllable. Two examples are also given to illustrate the importance of...
