无穷维广义线性二次型问题的严格耗散性

Strict dissipativity for generalized linear-quadratic problems in infinite dimensions

Lars Grüne, Friedrich Philipp, Manuel Schaller

摘要:

在希尔伯特空间上分析了广义线性二次最优控制问题的严格耗散性。这里,术语"广义“是指包含二次项和线性项的费用函数。我们通过一个特殊的类李雅普诺夫二次型的可积性来刻画具有二次存储函数的严格预耗散性。此外,我们证明了在一个额外的代数假设下,严格预耗散性可以加强到严格耗散性。最后,我们将所得到的耗散性的特征与指数可检测性联系起来。

英文摘要:

We analyze strict dissipativity of generalized linear quadratic optimal control problems on Hilbert spaces. Here, the term ``generalized'' refers to cost functions containing both quadratic and linear terms. We characterize strict pre-dissipativity with a quadratic storage function via coercivity of a particular Lyapunov-like quadratic form. Further, we show that under an additional algebraic assumption, strict pre-dissipativity can be strengthened to strict dissipativity. Last, we relate the obtained characterizations of dissipativity with exponential detectability.
