The aim of our project is to design the PID controller using LabVIEW. The designing software use for
this purpose is LabVIEW developed by National Instruments. We also intend to use a DAQ card by ADAM model
4022T and also USB to RS485 converter UD2535-U of milestone for interfacing computer with the hardware. The
hardware is a Multiloop Trainer Kit mounted with a tank whose level has to be controlled using a feedback control
loop. The feedback control loop is form by a tank, level sensor, controller, I to P converter and control valve. The
designed soft PID controller will replace the electronic PID on trainer loop kit.
