I will have to work on a project about stabilization through nonnegative control. I got some articles about it, which mainly talk about controllability. But, why do we even want stabilization through nonnegative control?
$$\dot{x} = Ax+Bu$$
I know it means that input $u$ is positive, but why do we want this $u$ to be positive?
Hope somebody can help me :)
