Fuzzy Adaptive PID algorithm is based on the classic PID fuzzy control rule base is added to establish the purpose of this library is the algorithm can own to change P , the I, the value of D.
Take control of the temperature rising process, the beginning of time, the desired temperature can quickly rise to the end of temperature fluctuations as small as possible and to stabilize the temperature at the target temperatures (it is best not to exceed). At this time, if the use of the classical PID control, then the time value of P is constant, but we hope that when he started as large as possible. Join the rule base, you can achieve, you can use the statement
if cold then increase the heat
Of course there are:
if hot then cold to increase
To quickly change the temperature.
Like we use in the winter cold feet, cold water + = cold feet feel very cold, can not wait to want to hurry up hot water, so we add hot water, not warm water.
This should be the most popular understand.
