中文摘要: 本项目首先研究非Lipschitzian半群的一些重要性质,并运用零点扰动与构造正则的Hausdorff非紧性测度技巧结合Banach空间几何理论和不动点理论研究抽象空间中非局部(脉冲型)微分包含(周期)解的存在性。拟讨论在半群没有紧性甚至等度连续性以及非局部项具备不同拓扑时解的存在性,并将引入殆非扩张曲线的概念,希望利用殆非扩张曲线的性质研究解的渐近行为。其次,把微分包含的相关研究结果应用到分布参数控制系统中,具体讨论由抽象空间中微分包含所描述的无穷维控制系统的可控性问题。最后,我们拟讨论由非局部微分包含描述的分布参数系统的一类最优控制问题,例如电能转换成热能过程中,在给定的性能指标集中寻找最优控制使得电能的总消耗达到最小的最优控制问题。本项目预期研究结果不仅对微分包含理论的完善和发展具有积极的意义,还将对其他相关研究领域,如无穷维动力系统、控制论和最优化等理论的研究具有十分重要的意义。

英文摘要: In this project we shall first study some important propeties of non-Lipschitzian semigroup and deal with the existence of (periodic) solutions of nonlocal (impulsive) differential inclusions in abstract spaces. By using the method of zero perturbation, the technique of constructing regular Hausdorff measure of noncompactness and the theory of geometry of Banach spaces and fixed points, we shall discuss the problems of differential inclusions without assumptions on the compactness or equicontinuity of the semigroup and consider the above problems when nonlocal items have different topology. We shall also introduce the concept of almost non-expansive curves and want to investigate the asymptotic behaviour by utilizing the properties of almost non-expansive curves. Subsequently, related research results of differential inclusions will be applied to the distributed parameter control system. We shall discuss in detail controllability problems of infinite dimension control system described by abstract differential inclusions in Banach spaces. Finally, we shall investigate a class of optimal control problem of distributed parameter system described by nonlocal differential inclusions. For example, during the process of electric energy being converted into heat, a typical problem is to find at least one optimal
