Equilibrium and Feedback
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.
Types of equilibrium
Static Equilibrium
Steady-State equilibrium
Steady-State Equilibrium
an average condition where the
overall situations remains fairly
constant.
Over time, inputs into the system
equals output, so there is no net
change.
Feedback
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.
Types of feedback
Positive feedback :
seeks to increase the output that
caused it
Negative feedback:
seeks to cancel the output that caused
it
