Answer Posted / murthy
PID- proportional integral and derivative
there different types of controlling techniques,
combinations of these parameters in designing controllers.
it depends on what type of errror occurs in ur
system,deviation from ur set point,time u want ur
controller to take action.
if u want quick acting one then go for only proportional
controller,the disadvantage is you get higher deviation.
if u want to minimze error (measured-set value) go for
integrated controller,disadvantage-your final forms cyclic
fluctuations.
derivative is taken into acount when u want zero cycling
always it is not suggeted to go for PID controller,as it is
costly,ur system may not need it at all.for eg if u want to
control level of a tank with 2 feeds and one withdrawl u
dont need integral action so u can go for PD controller
