Data-driven parameterizations of suboptimal LQR and H2 controllers
Henk J. van Waarde, Mehran Mesbahi
In this paper we design suboptimal control laws for an unknown linear system on the basis of measured data. We focus on the suboptimal linear quadratic regulator problem and the su…
Global Convergence of Policy Gradient for Sequential Zero-Sum Linear Quadratic Dynamic Games
Jingjing Bu, Lillian J. Ratliff, Mehran Mesbahi
We propose projection-free sequential algorithms for linear-quadratic dynamics games. These policy gradient based algorithms are akin to Stackelberg leadership model and can be ext…
Time scale design for network resilience
Dillon R. Foight, Mathias Hudoba de Badyn, Mehran Mesbahi
In this paper we consider the -norm of networked systems with multi-time scale consensus dynamics. We develop a general framework for such systems that allows for ed…
Augmented State Feedback for Improving Observability of Linear Systems with Nonlinear Measurements
Atiye Alaeddini, Kristi A. Morgansen, Mehran Mesbahi
This paper is concerned with the design of an augmented state feedback controller for finite-dimensional linear systems with nonlinear observation dynamics. Most of the theoretical…
Strong Structural Controllability of Signed Networks
Shima Sadat Mousavi, Mohammad Haeri, Mehran Mesbahi
In this paper, we discuss the controllability of a family of linear time-invariant (LTI) networks defined on a signed graph. In this direction, we introduce the notion of positive…
LQR through the Lens of First Order Methods: Discrete-time Case
Jingjing Bu, Afshin Mesbahi, Maryam Fazel +1
We consider the Linear-Quadratic-Regulator (LQR) problem in terms of optimizing a real-valued matrix function over the set of feedback gains. Such a setup facilitates examining the…
