Reference Control Architecture In The Presence Of Measurement Noise And Actuator Dynamics, Gerardo De La Torre, Tansel Yucelen, Eric Johnson Jan 2014

Reference Control Architecture In The Presence Of Measurement Noise And Actuator Dynamics, Gerardo De La Torre, Tansel Yucelen, Eric Johnson

Mechanical and Aerospace Engineering Faculty Research & Creative Works

In this paper the command governor-based model reference control architecture is developed and analyzed for uncertain dynamical systems in the presence measurement noise and actuator dynamics. Specifically, the command governor is a dynamical system that adjusts the trajectory of a given command in order to enable an uncertain system to be able to follow an ideal reference system capturing a desired closed-loop dynamical system behavior both in transient-time and steady-state. In this paper, we present modifications to the original command governor approach in order to increase its robustness properties against measurement noise and actuator dynamics. In particular, the modified architecture …


Conflict Minerals And The Law Of Pillage, Patrick J. Keenan Jan 2014

Conflict Minerals And The Law Of Pillage, Patrick J. Keenan

Chicago Journal of International Law

The illicit exploitation of natural resources-often called conflict minerals-has been associated with some of the worst violence in the past half-century, especially in the Democratic Republic of the Congo. Prosecutors and scholars have struggled to develop legal tools to adequately hold accountable those who have been responsible for the exploitation of civilians and resources in conflict. The most common legal tool, the crime of pillage, has been inadequate because it has been applied only to discrete, relatively small episodes of theft. As important as it has been, the episodic theory is of limited utility when applied to what have been …
