Control method of urban water service pipe network water supply system under external disturbance input

Abstract

The invention discloses a control method of an urban water service pipe network water supply system under external disturbance input. The control method comprises the following steps: step S1, establishing a state space model about the water yield change of the urban water service pipe network water supply system; step S2, designing a state feedback controller about the water yield change of the urban water service pipe network water supply system; step S3, verifying the positivity of the urban water service pipe network water supply system under the state feedback controller; step S4, verifying the progressive stability of the urban water service pipe network water supply system under the state feedback controller; and step S5, computing the weighted L1 gain of the water supply pipe network water supply system. Through the matrix decomposition, the input disturbance control and the weighted L1 gain performance analysis and like technology, the effective control on the safety water supply of the urban water service pipe network water supply system is realized, and the problem that the water supply is unstable and the water supply is insufficient in the water supply process can be effectively solved.

Description

technical field

[0001] The invention relates to the field of automation technology, in particular to a reliable control method for solving the problem of insufficient water supply in an urban water supply system by controlling the water volume or the opening value of a pump station valve during the water supply process, which can be used in the water supply process of the urban water pipe network water supply system. Background technique

[0002] Water is the source of life and the substance that people rely on for survival. With the high quality of life today, people's demand for water is increasing day by day, and urban water supply is often unstable, which not only causes unbalanced water supply, but even insufficient water resources. areas with no water available. Therefore, we need to rationally allocate water resources in various regions and design a reliable urban water supply system. The water supply system of urban water pipe network is composed of water source, pu...
