系统级综合的鲁棒性能保证

Robust Performance Guarantees for System Level Synthesis

Nikolai Matni, Anish A. Sarma

摘要:

我们推广的系统级综合框架定义的有界因果线性算子的系统,并使用此参数化之间的连接强大的系统级综合和经典的结果从鲁棒控制文献。特别是,利用L1鲁棒控制的结果,我们表明,充要条件的鲁棒性能的因果有界线性不确定性的系统动态可以转化为凸约束的系统响应。我们利用这种连接表明,这些条件自然允许将延迟,稀疏性和局部约束的系统响应和控制器的实现,使这些方法被应用到大规模的分布式控制问题-据我们所知,这些是第一个这样的强大的性能保证分布式控制系统。

英文摘要:

We generalize the system level synthesis framework to systems defined by bounded causal linear operators, and use this parameterization to make connections between robust system level synthesis and classical results from the robust control literature. In particular, by leveraging results from L1 robust control, we show that necessary and sufficient conditions for robust performance with respect to causal bounded linear uncertainty in the system dynamics can be translated into convex constraints on the system responses. We exploit this connection to show that these conditions naturally allow for the incorporation of delay, sparsity, and locality constraints on the system responses and resulting controller implementation, allowing these methods to be applied to large-scale distributed control problems -- to the best of our knowledge, these are the first such robust performance guarantees for distributed control systems.
