History

Creation

They were originally part of the race called Malthusians or Oans. When the Oans felt responsible for the catastrophic effects on the universe that the experiment one of their own, the renegade scientist Krona, had performed, they argued how to handle the situation. (Note: in the original version of the story, this experiment was supposed to have created evil itself.) Some Oans wanted to dedicate their immortal existences to contain evil; This group eventually became the Guardians of the Universe. Another group decided instead that it should be destroyed. This group left, eventually becoming The Controllers. (A later version of the story claims the controllers left over the Guardians decision to stop using their robot minions, the Manhunters.) Oa is a fictional planet located at the center of the universe in DC Comics. ... This article is about the Swedish unit of currency. ...

The Manhunters are a fictional race of robot warriors that exists within the universe of DC Comics. ...


Change

Just as the Guardians slowly changed their physical appearances over billions of years of existence, so did the Controllers. Originally, all Oans were blue-skinned humanoids; currently, the Controllers are pink-skinned and hairless. The Controllers moved to another dimension, and dedicated themselves to creating weapons that could be used to destroy evil beings if they became too dangerous. Among these are the Sun-Eaters, gaseous beings that can devour whole planets and stars, and the Miracle Machine, a device that can turn any thought into reality. Note that the Miracle Machine was too uncontrollable at first, so The Controllers avoided using it. The term humanoid refers to any being whose body structure resembles that of a human. ...


Darkstars

In recent times, The Controllers established their own corps of interstellar peacekeepers to compete with the Guardians' (The Green Lantern Corps) called the Darkstars. Many former members of the Corps joined the Darkstars after the Corps were destroyed. This team is now considered destroyed. The interstellar medium (or ISM) is a term used in astronomy to describe the rarefied gas and dust that exists between the stars (or their immediate circumstellar environment) within a galaxy. ...

Publications about 'controllability' (2366 words)
This paper shows that, for time varying systems, global asymptotic controllability to a given closed subset of the state space is equivalent to the existence of a continuous control-Lyapunov function with respect to the set.
Weak controllability of bilinear systems is preserved under sampling provided that the sampling period satisfies a condition related to the eigenvalues of the autonomous dynamics matrix.
It is shown that a control system in Rn is asymptotically controllable to the origin if and only if there exists a positive definite continuous functional of the states whose derivative can be made negative by appropriate choices of controls.
Controllability - Wikipedia, the free encyclopedia (760 words)
Controllability is an important property of a control system, and the controllability property plays a crucial role in many control problems, such as stabilization of unstable systems by feedback, or optimal control.
Controllability and observability are dual aspects of the same problem.
Note that controllability does not mean that once you reach a state that you will be able to keep it there, merely that you can reach that state.
