Equilibrium / Equilibria


Equilibrium means balance. A system that does not tend to undergo any change of its own accord but remains in a single, fixed state is said to be in equilibrium.
There are two types of equilibrium:
  • Static Equilibrium ( this is unnatural and is very unlikely to happen in an uncontrolled environment)
  • Steady-State equilibrium

Steady-State Equilibrium
Steady State equilibrium is an average condition where the overall situations remains fairly constant. Over time, inputs into the system equals output, so there is no net change.

In order for a system to maintain a steady state, it must be able to self regulate. Self regulation is usually controlled by negative feedback and positive feedback mechanism. A system will not usually exist in steady state.
