Embodiment Construction

[0039] A rainwater discharge control method for an urban water system, comprising:

[0040] (1). Establish the state space model of the controlled object:

[0041] (1-1). Collect the water level value, pipeline displacement and water velocity data information of the drainage pipes and rivers in the urban water system through data acquisition instruments, flow meters, and water pressure meters; based on the spatial distribution information and water quality of urban drainage pipes and rivers Based on the principle of mechanics, the Saint-Venant equation of the urban water drainage system is established, and combined with the measured water data, the following state equation is established:

[0042]

[0043] where x(k)∈R 3 Represents the state vector of the water flow in the pipeline or river channel of the drainage system at time k, y(k)∈R 1 Indicates the measurement output of the drainage system at time k, symbol means n 0 column vector of dimensions;

[0044] x(k)=[x...

Abstract

The invention discloses a rainwater discharge control method of an urban water system. At present, rainfall cannot be accurately predicted by the urban water system, great difficulties are brought toan urban drainage system, and urban water logging is prone to being triggered. The rainwater discharge control method comprises the establishment of a state space model of a controlled object, a static output feedback controller structure and the solution of a static output feedback controller. According to the rainwater discharge control method, based on a markov jump system with a piecewise constant transition probability, a mathematical model of rainwater discharge in an urban drainage network is established. The corresponding static output feedback controller is designed by using a stochastic analysis method and a matrix singular value decomposition method. According to the rainwater discharge control method, the used static output feedback controller is simple in structure, only external measurable signals need using, the static output feedback controller is easy to obtain and good control requirements can also be met simultaneously. An effective method for the control of the urban drainage system is provided, and the occurrence of the urban water logging can be reduced.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and relates to a rainwater discharge control method for an urban water system, in particular to a Markov jump system with a piecewise constant transition probability, which uses static output feedback control to realize the rainwater discharge control of the urban water system. The discharge control method realizes the effective adjustment of rainwater discharge in the case of heavy rainfall in the urban water system. Background technique [0002] Heavy rainfall is a serious challenge to the drainage system of modern cities, especially cities that are often affected by typhoon weather disasters. For example, Fuzhou and Wenzhou, which are located on the southeast coast of my country, are affected by heavy rainfall brought by typhoons all year round, and urban areas are prone to waterlogging. According to statistics, in 2017, the rainfall in some major cities in coastal provinces, such a...
