 Category :: Instrumentation Posted By : koolfire 
 :Q:  Can you explain drawbacks between P,I,D & PID controller
A :: P,PID controller'S are used to tune the output to a desired value. however for proportional controllers it always has a steady state error as the output will never reach the desired value but will be close to it. For  a PID controller due to its integral and derivative action(rate of change of error), it cancels out the steady state error.
