In [[applied physics]], the concept of '''controlling self-organized criticality''' refers to the control of processes by which a [[self-organized]] system dissipates [[energy]]. The objective of the control is to reduce the probability of occurrence of and size of [[energy dissipation]] bursts, often called ''avalanches'', of self-organized systems.  Dissipation of energy in a [[self-organized criticality|self-organized critical]] system into a lower energy state can be costly for society, since it depends on avalanches of all sizes usually following a kind of [[power law]] distribution and large avalanches can be damaging and disruptive.
