The deviation rectification control method comprises the steps that a deviation rectification principle model of a shield tunneling machine is constructed; the deviation rectification principle model comprises a deviation rectification track curve; the minimum deviation rectification radius of the deviation rectification principle model is determined; the minimum deviation rectification radius of the deviation rectification principle model is the curvature radius of the deviation rectification track curve; preset shield tunneling machine parameters are processed by using an artificial ant colony algorithm to obtain an optimal feature subset; according to the minimum deviation rectification radius and the optimal feature subset, a deviation rectification mathematical model of the shield tunneling machine is constructed; based on the deviation rectification mathematical model, the optimal feature subset is optimized through an artificial bee colony algorithm to obtain control parameters; and a tunneling posture of the shield tunneling machine is controlled to rectify deviation according to the control parameters. The optimal feature subset can be screened out by introducing the ant colony algorithm, and the optimal feature subset is used as an initial population of the artificial bee colony algorithm, so that the solving quality can be improved, the deviation rectification precision can be improved, and a better deviation rectification effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of general control or adjustment systems, and in particular relates to a deflection correction control method and device for shield tunneling posture. Background technique [0002] With the development of urbanization and the gradual increase of urban population, the construction of subway tunnels has become an important measure to relieve traffic pressure and improve the urban environment. Open cut method and shield method are the main methods of subway tunnel construction. Using the open-cut method, the initial masonry and other work are completed in the open air. Factors such as terrain, landform, construction environment, and weather have a great influence on the construction, which limits the application range of the open-cut method. The shield tunneling method belongs to the underground excavation method. During the implementation, the shield tunneling machine completes the excavation, initial laying,...

Problems solved by technology

However, because the artificial bee colony algorithm is easy to fall into the problem of local optimum, which leads to low optimization accuracy and slow convergence speed, the accuracy of the solution results of the deviation correction model is reduced, and the practicability is not strong.
