# Control Theory and Optimization Group

## Research

Control theory and optimization is a core research area in applied mathematics in the LSU Department of Mathematics. Control theory studies the effects of different time- or state-dependent parameters in dynamical systems. The parameters are called controls, and are used in applications to model the effects of possible forces that can be applied to systems to achieve prescribed objectives, such as ensuring that all solutions of the dynamical systems converge to an equilibrium. State-dependent controls are called feedback controls. The current members of the group and their students are listed below. You can click on their names to find out about their activities. The director and contact person for the group is Professor Michael Malisoff. Group members are studying feedback control and observer design, nonsmooth analytic methods, numerical methods, and other cutting edge topics. Their research has involved adaptive control, Hamilton-Jacobi equations, marine robotics, power electronics, state constrained and delayed systems, tracking and stability problems for bioreactors, and nonlinear programming. The group has a strong record of extramural support. Group members have been awarded more than $2.4 million as Principal Investigators of federal research grants. A total of 22 Ph.D. students received their degrees under the supervision of group members, and the group provides a supportive environment for collaboration with, and mentorship of, its postdoctoral researchers. Group members have produced many research publications in the top Automation and Control Systems journals, and have presented many conference presentations and seminars at leading universities. They have served on the editorial boards of many journals. The group organizes a departmental Control and Optimization Seminar series, and interacts with engineering faculty who also conduct research in systems and controls. Their outreach and teaching includes the Mathematics Consultation Clinic, which is an applied mathematics capstone course. Their research, teaching, and outreach has been reported on in several magazine and other news articles. ## Current Professorial Group Members: 1.
