Safe Exploration for Nonlinear Processes Using Online Gaussian Process Learning
Stefano Tonini, Soroush Rastegarpour, Hamid Reza Feyzmahdavian +2
This paper proposes a safe data-driven control framework for nonlinear systems with partially known dynamics. The method ensures stability and constraint satisfaction during online…
Stability Analysis of Monotone Systems via Max-separable Lyapunov Functions
Hamid Reza Feyzmahdavian, Bart Besselink, Mikael Johansson
We analyze stability properties of monotone nonlinear systems via max-separable Lyapunov functions, motivated by the following observations: first, recent results have shown that a…
Sub-homogeneous positive monotone systems are insensitive to heterogeneous time-varying delays
Hamid Reza Feyzmahdavian, Themistoklis Charalambous, Mikael Johansson
We show that a sub-homogeneous positive monotone system with bounded heterogeneous time-varying delays is globally asymptotically stable if and only if the corresponding delay-free…
Asymptotic Stability and Decay Rates of Homogeneous Positive Systems With Bounded and Unbounded Delays
Hamid Reza Feyzmahdavian, Themistoklis Charalambous, Mikael Johansson
There are several results on the stability of nonlinear positive systems in the presence of time delays. However, most of them assume that the delays are constant. This paper consi…
Exponential Stability of Homogeneous Positive Systems of Degree One With Time-Varying Delays
Hamid Reza Feyzmahdavian, Themistoklis Charalambous, Mikael Johansson
While the asymptotic stability of positive linear systems in the presence of bounded time delays has been thoroughly investigated, the theory for nonlinear positive systems is cons…
Optimal Distributed Controller Design with Communication Delays: Application to Vehicle Formations
Hamid Reza Feyzmahdavian, Assad Alam, Ather Gattami
This paper develops a controller synthesis algorithm for distributed LQG control problems under output feedback. We consider a system consisting of three interconnected linear subs…
Distributed Output-Feedback LQG Control with Delayed Information Sharing
Hamid Reza Feyzmahdavian, Ather Gattami, Mikael Johansson
This paper develops a controller synthesis method for distributed LQG control problems under output-feedback. We consider a system consisting of three interconnected linear subsyst…
