temperature control, level control

The trainer provided a comprehensive experiment, introduced the basic principles of control engineering, and used pressure control examples. The air pressure control system is a second order system. It includes an in-line pressure vessel connected by a flow control valve. An additional valve on the other tank allows air to be used as much as possible to simulate a disturbance variable. The pressure sensor measures the pressure of the two ships. The controller used is the most advanced digital industrial controller in a country. The actuator in the loop is the standard current signal input of the pneumatic control valve. The control variable X and the manipulated variable y are directly drawn on the integrated dual-channel line recorder. In addition, the variable can be tapped as an analog signal in the laboratory jack of the switch cabinet. This enables external recording equipment such as an oscilloscope or flat-panel plotter.

This equipment takes flow control as an example to give a comprehensive experimental introduction to the basic principles of control engineering. All components are clearly placed on the vertical front panel. The large-format process diagram is helpful for understanding. The water pump transports the water in the storage tank to the pipe section. The flow rate is measured by the paddle wheel sensor. The transparent float flowmeter enables the control process to be clearly observed. The controller used is the most advanced digital industrial controller. The actuator in the control loop is an electric control valve. The ball valve in the pipeline section allows defined disturbance variables to be generated. The control variable x and the manipulated variable y can be used as analog signals for laboratory jacks. This allows external recording equipment such as plotters or oscilloscopes to be connected.
