PhD on Mathematical and computational approaches for analysis and control of complex dynamical systems
The Katholieke Universiteit Leuven

The mathematical modeling of complex engineering and biological systems naturally leads to a decomposition into simpler subsystems. Modelling the dynamics of subsystems typically leads to differential equations, while their interconnections give rise to algebraic equations. Furthermore, the fact that the transfer of material, energy and information (i.e. signal transmission) between subsystems is mostly not instantaneous, may be modeled by delay elements. All these model components can be integrated into one so-called Delay-Differential Algebraic Equation (DDAE) model. DDAE models are extremely flexible and amenable for a systematic and automated modeling procedure, at the basis of simulation, monitoring, prediction and control, yet what hinders a widespread use it that, inherently to the rich and sometimes non-trivial behavior of their solutions, there are still many open questions and mathematical challenges to be overcome, on which the project focuses.The PhD program will be built around three pillars. The first one concerns investigating theoretical properties of the models and developing of mathematical analysis methods (to assess, for example, the stability of the modeled system or its performance). The second pillar concerns uncertainty quantification, i.e., assessing the impact of modeling errors on the results of the analysis, thereby respecting and exploiting the structure of the overall system. Within the third pillar, the aim is to make the leap from analysis to the design of feedback controllers. Here, we assume that the described physical system can be actuated and that online measurements are available, which can then be used to alter the performance, robustness or resilience of the system in a desirable or optimal way. The design of the control law, which translates the measurements into the actuation, will be mainly model based, but complementary data-driven design methods and implementations will also be explored.
The focus of the over arching project will be on mathematical / algorithmic innovations and control theory, but a close link with engineering applications will be ensured throughout its execution, which enables a validation of the results and may inspire novel research questions. In this respect, the PhD project benefits from the unique position of the hosting NUMA section of KU Leuven as a very large applied mathematics center operating within a Faculty of Engineering Science, and it is well integrated with the many collaborations and ongoing projects on both the methodological and application side.Prerequisites are a solid basis knowledge of linear algebra and differential equations, a strong interest in a mathematically oriented project, enthusiasm and a critical mindset. Familiarity with control theory and good programming skills are not required but may be an advantage.
