Experiments

  • Fundamentals of control engineering based on the example of a pressure  control system with Pt1 behaviour
  • Open loop control response
  • Effects of different controller parameters and methods on the response of  the closed loop system
  • Recording of step responses (Reference variable / Disturbance variable)

Pressure control training system offers to learn the basic fundamentals control engineering. The experimental set-up is mounted on a housing which accommodates all the electronics. The pressure tank is charged with compressed air by a diaphragm gas pump. The advantage of the dial-gauge manometer is that the pressure in the tank can be observed directly at any time. The pressure is measured using a pressure sensor. The sensor output signal is sent to the software controller. The output signal from the controller influences the speed of the diaphragm gas pump and hence the flow rate. An air consumer is simulated by way of a flow control valve. A solenoid valve through which air can escape can be activated by the software to investigate the influence of disturbance variables. The powerful state-of-the-art 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.
