Description

System

The Coupled Tanks set-up is a model of a chemical plant fragment. Very often tanks are coupled through pipes and the reactant level and flow has to be controlled. The Coupled Tanks experiment is designed so that the system can be configured. The Coupled Tanks system has 4 translucent tanks each with a pressure sensor to measure the water level. The couplings between the tanks can be modified by the use of seven manual valves to change the dynamics of the system imposing the use of different controllers. Water is delivered to the tanks by two independently controlled, submersed pumps. Step disturbances generation is provided by four manual valves. Drain flow rates can be modified using easy-to-change orifice caps.

The system can be operated with MATLAB™ or LabVIEW™.

Objectives

  • Non-linear model
  • Linearisation
  • Linear model simulation
  • 1 tank & 2 tank identification
  • PID control of water levels in top tanks
  • PID control of water levels in bottom tanks
  • Parallel PID control in two double tank columns
  • Cross-coupling introduction & analysis

The equipment set incorporates student experiments which can be carried out in a laboratory safely using safety extra-low voltage. Experiment instructions are contained in a manual in either printed or digital form.

A LabVIEW™ or MATLAB™ license is required for this experiment and is not included in the scope of delivery.
The equipment can require additional software modules.

Target Group

A training program made for the advanced training study programs at applied technology universities and technical universities. Knowledge of classic control engineering is a prerequisite.
