Banach空间中的非线性脉冲积微分系统和最优控制

论文摘要

在本文中,用算子半群理论较系统地研究了无穷维Banach空间X中带无界算子的非线性脉冲积微分系统和最优控制。即讨论下列三类积微分方程:(a)单纯型时变非线性脉冲积微分方程(b)混合型非线性脉冲积微分方程(c)混合型时变非线性脉冲积微分方程其中∧={t1,t2,…,tn}(?)(0,T),0=t0<t1<t2<…<tn<tn+1=T,A是C0-半群的无穷小生成元,{A(t)|t∈[0,T]}是闭稠定线性算子族,积分算子G和S是非线性算子,Ji(i=1,2,…,n)是一非线性映射,△x(ti)=x(ti+0)-x(ti-0)=x(ti+0)-x(ti),且Ji决定了状态x在ti时刻的跃度。对方程(1),在分数次幂空间中给出了PC-α-温和解的存在唯一性以及对初值的连续依赖性,相应的Bolza问题最优控制的存在性,并导出了最优化条件。在方程(2)中,为了克服混合型积分算子S的困难,建立同时带脉冲、混合型积分算子的Gronwall不等式和Banach空间PC([0,T],X)中的Ascoli-Arzela定理,用Leray-Schauder不动点定理证明了PC-温和解的存在性。同时证明了一类Lagrange问题的最优容许对的存在性。最后,一个例子展示了我们的结果。对方程(3),在分数次幂空间中建立带脉冲、混合型积分算子和奇性的Gronwall不等式,证明了PC-α-温和解的存在性,也证明一类Lagrange问题的最优容许对的存在性。最后,用一个例子展示了我们的结果。
