By using a PID controller we can eliminate the offsets and
unwanted oscillations of the process variables we are
dealing with and will get the process variable value close
to the set point value.For that we need to tune the
controller properly and select proper values for P,I and D

plz tell me clearly about PID.."when v have to change I value,D value,GAIN??
