Multivariable control trainer is designed for teaching the basic level control principles and advanced study in complex systems for control engineering. It is a combination of four tank systems, usually also known as Quadruple Tank system. The setup consists of supply water tank with two variable speeds positive displacement pumps for water circulation, five transparent process tanks fitted with level transmitters, rotameters and flow dampers. The process signals from level transmitters are connected to Multifunction I/O & NI-DAQMX which is connected to computer through USB port communication. The process parameters are controlled through software and the output is fed to variable frequency drives used for the pumps. These units along with necessary piping are fitted on standalone support structure.
