AI Technical Summary

Technical Problem

Existing underwater robots are easily disturbed by water flow and spraying torque in pouring fluid solidified soil, resulting in severe deviations in attitude angles and swaying, and it is difficult for feedback closed-loop control systems to effectively correct them.

Method used

The attitude controller is used to calculate the anti-symmetric matrix by combining the water torque and the spray torque, and the reverse torque is outputted by the underwater thruster to offset the interference torque, maintaining the stability of the robot's attitude.

Benefits of technology

It effectively prevents the robot's attitude imbalance caused by water flow and spraying torque, ensuring the stability and accuracy of the casting process.

Abstract

The invention relates to the technical field of underwater construction, in particular to a scouring repair and detection composite function robot for flow-state solidified soil, which comprises a cabin body, an underwater propelling device, a control device and a pouring device. The control device is provided with an attitude controller, the attitude controller is used for determining an attitude control signal according to the hydrodynamic torque and the guniting torque, and the attitude control signal is used for driving the underwater propelling device. According to the method, the hydrodynamic torque and the guniting torque are input to the attitude controller, the attitude controller calculates the total disturbance torque, then the antisymmetric matrix is calculated according to the disturbance torque, and the control parameters are output according to the antisymmetric matrix to adjust the propelling torque of the underwater propeller. The control parameters are calculated through the attitude controller according to the disturbance torque, so that the underwater propeller outputs the reverse propelling torque, the disturbance torque is counteracted to realize constant angular momentum, and attitude imbalance caused by interference of the robot during operation is prevented.
