Embodiment Construction

[0055] Step 1. Establish the state space model of the urban water supply system. The specific method is: first collect the data of the water volume change in the water supply tank in the urban water supply system, and use these

[0056] The data establishes the state space model of the urban water supply system in the following form:

[0057]

[0058] Among them, x(t)=[x 1 (t),x 2 (t),...,x n (t)] T Indicates the amount of water in the water supply tank at time t, n indicates the number of water tanks, u(t)∈R m is the opening degree of the water valve on the water tank or the water pipe at time t, m represents the number of water valves, R m is an m-dimensional real column vector. A and B are the weighted matrix composed of the data collected by the sensor. Consider the positivity of the actual system, that is, x(t), u(t) is always non-negative, here it is assumed that the water supply system is a positive system model, A is a Metzler matrix (the off-diagonal elements...

Abstract

The invention discloses a random saturation control method of a water affair water supply system. The method comprises the following specific implementation steps of: the step 1, establishing a statespace model of an urban water supply network; the step 2, proposing a system matrix representation method; the step 3, considering a modal transition probability, and solving the description problem of the random system; the step 4, constructing a saturation state space model of the water affair system; and the step 5, designing a control law of the water quantity in the water supply tank of the water supply system under saturation limitation. By means of data acquisition, model establishment, saturation control, controller design and the like, the design method of the random saturation controller of the urban water supply system is determined, the water quantity and water valve saturation problem of the water supply system can be effectively controlled by utilizing the method, safe operation of the water supply system is guaranteed, and the method has the good performance indexes.

Description

technical field [0001] The invention belongs to the field of automation, and relates to methods such as saturation control and state feedback control in the automation technology. The above method is used to achieve random saturation control of urban water affairs systems, and can be used in water supply systems of urban water affairs. Background technique [0002] Water is the material condition that people depend on for survival. In the 21st century, with the continuous acceleration of the urbanization process, the excessive consumption of resources, the pollution of the environment, and the destruction of ecology. In the process of urban construction, problems such as shortage of water resources, difficulty in water supply, and saturation of pipe network actuators began to appear. The safe supply of water resources has gradually become an indispensable part of urban development. [0003] The water supply system of a modern city is an important part of the overall urban ...
