Conditions for strict dissipativity of infinite-dimensional generalized linear-quadratic problems

Lars Grüne, David Muff, Manuel Schaller

摘要:

在希尔伯特空间上,以包含线性项和二次项的代价泛函为代价,得到了线性发展方程最优控制严格耗散的充分条件.我们表明,严格的耗散性与特定的存储功能是等价的椭圆的Lyapunov型运营商。此外,我们证明下的谱分解假设的基础生成器和正交条件下产生的子空间,这种椭圆性质下的可检测性假设。我们通过一个一维区域上的热方程的例子来说明我们的结果。

英文摘要:

We derive sufficient conditions for strict dissipativity for optimal control of linear evolution equations on Hilbert spaces with a cost functional including linear and quadratic terms. We show that strict dissipativity with a particular storage function is equivalent to ellipticity of a Lyapunov-like operator. Further we prove under a spectral decomposition assumption of the underlying generator and an orthogonality condition of the resulting subspaces that this ellipticity property holds under a detectability assumption. We illustrate our result by means of an example involving a heat equation on a one-dimensional domain.
