Problems solved by technology

Because some ports are restricted by natural conditions or considering the cost of channel construction, the channel width and water depth in the port are limited, and ships are prone to collisions, grounding and other accidents in narrow waterways. These limiting factors often cause serious ships to wait. Extended non-operational hours in port leading to vessel congestion in port
Just like Shanghai Port, due to the uncertain and bad weather, the efficiency of port operation is reduced, and a large number of ships are stranded in the port. Some ships in the port cannot leave in time, and the berth capacity of the port is limited. congestion

Embodiment Construction

[0105] In order to better understand the object, structure, and function of the present invention, a glossy control method of a portable capacity of a port ship in a port ship will be described in detail below in conjunction with the accompanying drawings.

[0106] like figure 2 As shown, a portable control method of a port ship carrying capacity, the specific steps are as follows:

[0107] Step 1, first collect the ship traffic of the port, using the collected data to establish the status space model of port ship's mobile control system, the form is as follows:

[0108] X (k + 1) = α σ(k) (k) sat (a σ(k) X (k) + b σ(k) u (k))

[0109] + (1-α) σ(k) (k)) SAT (a σ(k) X (k) + b σ(k) u (k)),

[0110] in, Indicates the number of ships in the number K sampling time, N indicates the number of berths in the port. For the control signal of the port ship traffic, M represents the number of port terminals, the function sat (·): Is the standard saturation function of vector value, is defin...

Abstract

The invention belongs to the field of automation technology and modern control, and discloses a control method for port ship bearing capacity saturation. By means of data acquisition, modeling, optimization control and the like, the ship transportation control method for the port is established, and the method can effectively solve the problem of congestion in the port caused by limitation of natural conditions and emergencies in the port. On the basis of a port ship dredging control system modeled by a positive switching system with random state saturation, an event trigger controller is designed, dredging of port ships is controlled in real time, and safe and efficient operation of a port is guaranteed.

Description

Technical field [0001] The present invention belongs to the field of automation technology and modern control, particularly to a port of the vessel carrying amount and distribution control method saturated. Background technique [0002] Marine transportation is the most important international logistics and transportation, through the use of its vessels to transport goods between ports in different countries and regions. Maritime transport of major technical equipment, including ships, waterways, ports and communications, navigation and other facilities, ports as an important maritime transport transport infrastructure, is a water and land transport equipment and conditions for ships safe access and berthing transportation hub, maritime transport focal point of the tool. In recent years, my country's marine transportation continue to maintain the trend of rapid development, an increasing number of large and very large ship is put into use. With the trend of large increases every ...
