Robust Model-Free Learning and Control without Prior Knowledge
Dimitar Ho, John Doyle
We present a simple model-free control algorithm that is able to robustly learn and stabilize an unknown discrete-time linear system with full control and state feedback subject to…
Scalable Robust Adaptive Control from the System Level Perspective
Dimitar Ho, John C. Doyle
We will present a new general framework for robust and adaptive control that allows for distributed and scalable learning and control of large systems of interconnected linear subs…
Online Adversarial Stabilization of Unknown Networked Systems
Jing Yu, Dimitar Ho, Adam Wierman
We investigate the problem of stabilizing an unknown networked linear system under communication constraints and adversarial disturbances. We propose the first provably stabilizing…
Distributed Linear Quadratic Regulator Robust to Communication Dropouts
Carmen Amo Alonso, Dimitar Ho, Jose M. Maestre
We present a solution to deal with information package dropouts in distributed controllers for large-scale networks. We do this by leveraging the System Level Synthesis approach, a…
Achieving Performance and Safety in Large Scale Systems with Saturation using a Nonlinear System Level Synthesis Approach
Jing Yu, Dimitar Ho
We present a novel class of nonlinear controllers that interpolates among differently behaving linear controllers as a case study for recently proposed Linear and Nonlinear System…
Three Dimensional Aggregation of Magnetic Particles
Alex Pai, Dimitar Ho, Ali Hajimiri
Magnetic drug delivery is a promising therapeutic because of magnetic fields' ability to permeate unperturbed in human tissue. One of the long-standing challenges in magnetic drug…
Separating Controller Design from Closed-Loop Design: A New Perspective on System-Level Controller Synthesis
Jing Shuang Li, Dimitar Ho
We show that given a desired closed-loop response for a system, there exists an affine subspace of controllers that achieve this response. By leveraging the existence of this subsp…
A System Level Approach to Discrete-Time Nonlinear Systems
Dimitar Ho
We will show that there is a universal connection between the achievable closed-loop dynamics and the corresponding feedback controller that produces it. This connection shows prom…
Online Robust Control of Nonlinear Systems with Large Uncertainty
Dimitar Ho, Hoang M. Le, John C. Doyle +1
Robust control is a core approach for controlling systems with performance guarantees that are robust to modeling error, and is widely used in real-world systems. However, current…
Passive-Aggressive Learning and Control
Dimitar Ho, Nikolai Matni, John C. Doyle
In this work, we investigate the problem of simultaneously learning and controlling a system subject to adversarial choices of disturbances and system parameters. We study the prob…
