Structure meets Data – System Representation for Trustworthy and Efficient Control

Sandra Hirche

Professor

Resumo: Data-driven models are increasingly employed to complement or replace first-principles models in modern control systems. Yet purely data-driven approaches often lack the guarantees on stability, safety, and generalization that control applications demand, and they typically require large amounts of data to perform well. This talk argues that the key to overcoming these limitations lies not in choosing between physics-based and data-driven modeling, but in systematically combining them: embedding structural knowledge — from physical laws to symmetries — directly into the learning process. We will present approaches to structured dynamic system representation using Gaussian processes. We show how exploiting structure improves data efficiency, yields calibrated uncertainty quantification, and enables formal guarantees on robust closed-loop stability and safety — key ingredients for trustworthy control. We illustrate the benefits of these structured representations on robotic and human-machine systems.

Uso de Informação Auxiliar na Identificação de Sistemas Não Lineares

Plenária Bottura-Castrucci

Resumo: A identificação de sistemas nasceu no contexto de sistemas representados como “caixas pretas”. Nesse cenário o objetivo é construir modelos exclusivamente a partir de dados dinâmicos, normalmente obtidos durante testes específicos. Quando não se tem outras informações sobre o sistema além desse conjunto de dados, a identificação caixa preta é uma ótima opção na construção de modelos. Um leve desvio dessas técnicas, conhecido como identificação semifísica, é composto de técnicas que utilizam conhecimento do sistema para determinar a estrutura matemática do modelo e os dados são empregados para estimar parâmetros. Nesta palestra desejamos dar um passo além da modelagem semifísica. Imaginamos que informação adicional do sistema não determina por completo a estrutura do modelo, sendo que em alguns casos ela está na forma de um conjunto de dados em estado estacionário. Alguns tipos de informação auxiliar úteis em identificação de sistemas são revistos, bem como procedimentos para levar a informação adicional em conta durante a construção de modelos. Esses métodos constituem parte do que se conhece por identificação “caixa cinza”. Dois estudos de caso são discutidos.

Stability and Signal Generator Agnostic Moment Matching

Abstract: Moment matching is a model reduction technique that allows the construction of reduced-order models preserving specific moments. These moments are associated with the steady-state output response of the system to be reduced, interconnected in an open-loop fashion with a signal generator. Model matching thus relies on strong stability properties and on the availability of a model of the signal generator.

To relax these requirements, in the first part of the talk we introduce a data-driven procedure for computing reduced-order models from input-output data generated by an agnostic signal generator. The moments are directly identified from the output of the system to be reduced, and the resulting reduced-order models achieve asymptotic matching.

To relax the stability requirements, in the second part of the talk we revisit the notion of moment matching by introducing the concept of closed-loop interpolation. This notion relies upon the construction of a novel class of signal generators, which are feedback-interconnected with the plant to be reduced, and allows the definition of moments and models for unstable systems. The existence of a family of models that parameterise all, possibly unstable, systems achieving moment matching in a closed-loop fashion is also presented.

Differentiable Control and GPU Parallelism: A New Optimization Framework for Robotics

Fabio Ramos

Professor

08/10/2026

Abstract: Massively parallel hardware has unlocked unprecedented computational power in robotics, shifting our analytical focus from finding a single motion to generating a diverse and resilient set of solutions. But how do we mathematically define or measure diversity in motion planning for robotics manipulators? In this talk, I will provide a probabilistic interpretation for diversity and show how tools designed for machine learning—such as differentiable programming languages and parallel computation on GPUs—can be utilized for large-scale probabilistic inference in planning and control. I will describe a powerful nonparametric inference method that leverages both differentiability and parallelism to provide posterior approximations for real-time Model Predictive Control (MPC), and task and motion planning. Finally, I will formulate diversity in trajectory planning through a new mathematical tool—signature transforms—that leads to highly resilient, next-generation motion planning methods capable of handling the uncertainties of real-world robotics manipulation.

Plenária Jovem Pesquisador

Resumo: Esta palestra apresenta resultados recentes sobre o controle de sistemas comutados por meio de ferramentas baseadas em grafos. Para a classe de sistemas comutados com modos lineares e em tempo discreto, são discutidas a construção de funções de Lyapunov e a síntese de controladores a partir de famílias de grafos com estruturas particulares. Será mostrado que, para uma classe específica de grafos, obtêm-se, pela primeira vez na literatura, condições convexas, expressas por LMIs, que são assintoticamente necessárias e suficientes para a estabilização sob comutação arbitrária. Em seguida, utilizando teoria de linguagens formais e autômatos, será apresentada uma extensão dessas ferramentas para cenários em que a estabilização sob comutação arbitrária não é possível. A palestra será concluída com uma breve discussão sobre perspectivas e desafios atuais em sistemas comutados.
