Analysis of Control Problem with Applications - ACPA
Control Theory and related areas of mathematical analysis constitute extremely active fields of modern mathematics research.
These fields involve both profound theoretical challenges and applications in domains as diverse as biology, environmental
sciences, engineering, and others.
This proposal is concerned with the search for new and innovative mathematical tools and knowledge to analyze problems
that originate in real-world activities. In modern mathematics, these advances are often achieved by combining techniques
and ideas from two or more distinct areas of research. In this project, we plan to use our background in applied mathematics
to analyze specific problems, using interdisciplinary approaches: Optimization, Numerical Analysis, Inverse Problems, Control
of Partial Differential Equations, Mathematical Programming, and Optimal Control.
The main general objective of this proposal is to consolidate the scientific work of the researchers participating in this project
to establish the first research group in Chile focusing on theoretical control and optimization problems. This group will
become an important scientific center in our country, where the mathematical community currently comprises approximately
170 researchers. Funding of this proposal should have a significant impact on our small community.
The members of this project have a strong foundation in applied mathematics, modeling, and related fields. This background
will contribute to a multidisciplinary approach to identify solutions to applied mathematics problems. To fulfill the main
objective of this proposal, we present the Scientific Objectives that constitute the core of the scientific research proposed in
SO1. Control of bioprocesses. In classical macroscopic models of bioprocesses, the biomass is viewed as a catalyst for the
conversion of substrates into products. One key issue is the optimization of the production of the synthesis product
or biomass. We will address the issue of optimizing bioreactors using both approaches, optimal control and adaptive
SO2. Sustainable exploitation of marine resources. Important fisheries are currently in a precarious situation. Mathematical
modeling can provide new and rigorous perspectives that can contribute to solutions. The models considered by
regulatory organisms are non-linear and age-structured, and they should be supported by experimental observations.
We plan to develop new theoretical tools in an effort to apply optimization and control techniques to realistic models.
SO3. Signal compression and recovery. The quality of signals depends on their storage and transmission, which usually
involves two major transformation steps: codification and reconstruction. Each of the two steps can be considered an
optimization problem. We plan to address this problem by applying constrained optimization algorithms to the original
infinite-dimensional signal spaces.
SO4. Control and inverse problems for Partial Differential Equations (PDEs). We primarily address controllability,
stabilization, and single-measurement inverse problems of PDEs. We will study the parameter-identification problems
of PDEs in relation to two kinds of mathematical models: those related to bioprocesses and fluid/solid problems in
SO5. Numerical analysis of control problems. We intend to combine the expertise of the researchers concerning the control
theory with numerical techniques to develop discrete controls that converge to continuous controls. Furthermore, we
intend to develop new strategies that allow us to study analytical and numerical methods for control problems to
obtain convergence and optimal convergence rates in both open-loop and closed-loop cases.
SO6. Inverse problems in earth sciences. In asymptotic wind models, the necessary wind data is only known by measu-
rements at certain points. We plan to study the optimal control problem of identifying the closest solution of the
asymptotic model to these data. Another issue is the inverse problem of recovering the thickness of the plate from
partial bathymetric measures, which has been widely studied. We plan to consider this inverse problem from both
theoretical and numerical perspectives.
The scientific objectives mentioned below are oriented entirely toward the development of mathematical theory in an inter-
