PID - Proportional plus Integral plus Derivative Controller.
This PID is used to reduce the steady state error obtained
in the output waveform. Steady state error does not allow
waveforms to settledown easier.
Proportional is used to process the present data of the
system and Integral is used to process the present plus
past data of the system where as derivative take the future
data also into account.
