• Fundamentals of control engineering based on the example of a rapid flow control system
  • Open loop control response
  • Recording of step responses (Reference variable / Disturbance variable)

Flow control training system offers to learn the basic fundamentals of control engineering. The experimental set-up is mounted in a housing which accommodates all the electronics. A piping system with two flowmeters is supplied with flow by a speed controlled pump from the transparent storage tank. The rotameter offers the advantage that the flow rate can be observed directly at any time. The flow rate is measured by a turbine wheel flow sensor. The sensor output signal is sent to the software controller. The output signal from the controller influences the setting of an electromagnetic proportional valve. To investigate the influence of disturbance variables, the pump speed can be altered by way of the software. The software designed is LabView. The software is an integral part of the training system, embodying the principle of hardware/software integration (HSI). It enables the experiments to be conducted and evaluated in a user friendly manner. The software has network capability. The link between the experimental unit and the PC is made via a USB port.
