What is Hysteresis?
The term hysteresis is used to designate the dependence of the
state of a system on its history. We may discriminate between two
types of hysteretic phenomena:
- Rate-dependent hysteresis usually occurs as a simple lag
between input and output. If the input is reduced to zero, the
output continues to respond for a finite time. When rate-dependent
hysteresis is due to dissipative effects like friction, it is associated
with power loss.
- Rate-independent hysteresis indicates a persistent memory of the
system to its past (loading history/response) that remains after the
transients have died out.
