Steam generator (SG) is one of the most important equipments in nuclear power plants. The water level of SG must be kept in a certain range to ensure the plants operate safely, reliably and economically. Nowadays, most SG water levels are controlled by PID in PWR plants. In this paper, ...

2, the water level control apparatus broadly includes at least one capacitive sensor 22 attached to an outer surface of a sidewall of a purified water storage tank (hereinafter, tank) 21 for storing water and a controller 23 controlling an amount of water to be supplied to the tank 21 ...
Water level regulation of irrigation canals represents a major challenge for control systems design. Those systems exhibit large dynamic variations in their operating conditions. To overcome this fact, robust controllers should be applied. The sliding mode control paradigm reveals this ability which make...
Water level control is highly important in industrial applications such as boilers in nuclear power plants. This paper analyzes the effectiveness of water level controller using fuzzy logic. The fuzzy controller is implemented in MATLAB and then simulated in SIMULINK to test the behaviour of the ...
Automatic Water Level Controller can provide a solution to this problem. The operation of water level controller works upon the fact that water conducts electricity. So water can be used to open or close a circuit. As the water level rises or falls, different circuits in the controller send ...
1, in order to ensure the normal operation of the liquid level controller, please check the input and output wiring again after installation, whether the probe cable is reliable or not. Move the probe up and down to bring it into contact with the water and simulate whether the water control...

The WCr controller is quite slow, hence the extraction rate increases slowly to the level where the drops in WCr occur. When the drops do happen, they are approximately equal to the drops experienced in Experiment 2. The adaptive gains are shown in Figure 11f,g. The gains for VT.2 are...
The signal transmission system uses a combination of acoustic communication for long-distance transmission at sea depth [9], optical for fast short-range communication in the depths of the sea [10], and radio waves for communication at sea level between the USV, relay station, and ground transm...
