摘要: In this paper, we use relaxation theory to study a class of relaxed infinite dimensional uncertain systems.We obtained the exisence and some important properties of solutions of relaxed systems first. Then the existence of optimal control of relaxed systems with a correspondingly relaxed cost functional was proved. Lastly, we showed that under some assumptions the set of original trajectories is dense in the set of relaxed trajectories and the relaxed control problem is equivalent to the original one.
