Invited Lecture: Feedback Control Meets Non-smooth Optimization

Time: 9:30 - 10:30
Room: L1, Building L
Chair: Sabine Pickenhain, Brandenburgische Technische Universität Cottbus

Feedback control can be viewed as designing a control mechanism to achieve stability and performance for a system described by ODEs or more general classes of differential equations. A simple formulation consist in computing  a controller  such that the loop formed by the system and the controller is stable and meets a variety of performance requirements. Performance typically refers to  damping improvement, reference tracking or disturbance and noise rejection, etc. The emergence of specialized non-smooth optimization techniques provides a novel approach to solving feedback design problems. This talk discusses different instances of the feedback design problem and shows how non-smooth optimization was used to overcome classical bottlenecks. Various real-world applications are introduced to illustrate its impacts for control engineers.
