PIDcotrol is mostly prefered in industries for process
control.it have three elements proportional,integral,diff,p
element is used to produce the contol o/pbased on present
error i/p,integral is used to avoid offset,derivative is
used for change in error i/p.pid has the advantages of all
three elements
