Towards Optimal Passive Feedback Control of LTI Systems under LQR Performance

Armin Gießler, Pol Jané-Soneira, Sören Hohmann

We study state-feedback design for continuous-time LTI systems with a control input and an external input-output pair. Our objective is to determine feedback gains that render the…

Data-Driven Continuous-Time Linear Quadratic Regulator via Closed-Loop and Reinforcement Learning Parameterizations

Armin Gießler, Felix Thömmes, Sören Hohmann

This paper studies data-driven approaches to the continuous-time linear quadratic regulator (LQR) problem based on two existing parameterizations, namely a closed-loop (CL) paramet…

Dynamic State-Feedback Control for LPV Systems: Ensuring Stability and LQR Performance

Armin Gießler, Felix Strehle, Jochen Illerhaus +1

In this paper, we propose a novel dynamic state-feedback controller for polytopic linear parameter-varying (LPV) systems with constant input matrix. The controller employs a projec…
