Embodiment example 1

[0064] Implementation case 1: The control algorithm steps of the main body of the three-capacity water tank are:

[0065] (1) Tank (T1), Tank (T2), and Tank (T3) are first set to be glass container 1, glass container 2, and glass container 3 in the main body of the three-capacity water tank respectively;

[0066] (2) Use CV1, CV2, CV3 to describe the connection valve switches between each glass container, wherein the connection valve switch CV3 is the water inlet valve;

[0067] (3) Use LV1, LV2, and LV3 to describe the drain valves of each glass container. Assuming that the cross-sectional area of ​​the three glass containers is s, the flow rate of the drain is controlled by manually adjusting the drain valve, and a recovery tank is installed under the drain valve for supply. water pump use;

[0068] (4) use T 1 and T 3 Respectively describe the water container into which the water pumped by the water pump flows;

[0069] (5) install the liquid level sensor detection orig...

Abstract

The invention relates to the field of liquid level control systems and particularly relates to a model-free adaptive-control water tank liquid level control system, which comprises a three-tank water main body, an electric control box and a control platform, wherein the three-tank water main body is internally provided with a liquid level transmitter, a three-phase brushless DC water pump, a liquid level sensor detection original and a data acquisition card. The model-free adaptive-control water tank liquid level control system has the beneficial effects that the first application of a model-free adaptive-control theory in the three-tank water liquid level control field plays an extremely important role in practice and promotion of the model-free control theory, a universal model for a model-free control algorithm is used for deducing a control law, a practical PLC algorithm program is converted, and thus, accurate control on the three-tank water liquid level is realized, the complicated control is realized by using the PLC program, and the universality is strong.

Description

technical field [0001] The invention relates to the field of liquid level control systems, in particular to a model-free adaptive control water tank liquid level control system. Background technique [0002] With the development of science and technology, the control problems in modern industrial production processes are becoming more and more complicated. In people's life and in some chemical and energy production processes, some liquid level or flow control problems are often involved, such as the supply of domestic water for residents, usually need to use a reservoir, the liquid level in the reservoir needs to be maintained Appropriate height, and some water treatment processes also need to control the liquid level in the reservoir. In addition, the production process involving liquid storage containers is also common, such as in the working process of nuclear power steam generators and ethylene engineering sewage For the automatic drainage treatment field of the treatme...
