DYSCO

DYNAMICAL SYSTEMS, CONTROL, AND OPTIMIZATION

Presentation

Research modern control and optimization technologies to help industry and society control and optimize their processes.

The main mission of the research unit DYSCO (Dynamical Systems, Control, and Optimization) is to develop new methodologies for the design of advanced multivariable controls that make systems react autonomously and optimally. Research revolves around model predictive control of dynamical systems, with specific emphasis on developing new algorithms for real-time convex embedded optimization, system identification and machine learning.

Besides focusing on algorithms and understanding their theoretical properties, research results are constantly applied to real-life problems of industrial, economic, and societal interest, such as in the automotive and aerospace industries, energy, process control, and financial engineering.

DYSCO is part of the research area in Computer Science and Engineering at the IMT School for Advanced Studies Lucca, Italy.

Research topics

Model Predictive Control (MPC)
Model Predictive Control (MPC) is widely adopted in industry for real-time control of large multivariable processes to optimize process operations under the best use of limited resources. The main idea of MPC is to choose the control action by solving an optimal control problem on line that minimizes a performance criterion over a future horizon, subject to constraints on process variables. The research unit investigates several issues in MPC, such as: stochastic MPC for constrained linear systems, decentralized and hierarchical MPC for spatially-distributed large-scale systems, MPC of networked systems based on wireless sensor feedback, explicit MPC and multiparametric programming for linear, hybrid, uncertain, and quantized systems.

Model predictive control

Numerical optimization Numerical Optimization algorithms for solving convex smooth and non-smooth mathematical programming problems, related to embedded MPC systems and to a large variety of areas, such as machine learning, various branches of engineering, and economics.

Hybrid systems
The hybrid models investigated by DYSCO are based on mixed-integer models for describing systems composed of both continuous and discrete dynamic components. Research investigations in hybrid systems include: modeling, model predictive control, verification and reachability analysis, observability analysis, fault detection and state estimation, scheduling and optimal control, stochastic hybrid systems, event-based hybrid systems, identification of hybrid models.

Systems Identification and Machine Learning approaches are investigated to learn dynamical models from data, with emphasis on linear parameter varying and nonlinear models.
