Abstract

The invention provides a motion control method of a jet device based on target driving, the method comprising: obtaining the abscissa and ordinate of the target in the coordinate system of the jet body; obtaining the yaw angle of the jet body according to the abscissa and the ordinate; The horizontal distance between the target and the jet body is input into the pitch angle prediction model to obtain the pitch angle of the jet body. The pitch angle prediction model is trained with the horizontal distance as the sample and the actual pitch angle as the label; For the pitch angle, the inverse kinematics is solved for the jet body, the rotation angle of the motor in the jet body is obtained, and the jet body is controlled to hit the target according to the rotation angle. The method proposed by the invention not only reduces the calculation steps of inverse kinematics solution, but also avoids the complicated mathematical modeling of the jet by using the neural network technology, and achieves the purpose of simplifying the calculation process and reducing the calculation complexity.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a motion control method of a jet device driven by a target. Background technique [0002] The conventional inverse kinematics problem of a manipulator means that the 6D pose of the end of the manipulator is known, and the rotation angles of all the joints of the manipulator are obtained. There are usually four methods to solve the inverse kinematics of the manipulator: analytical method, geometric method, iterative method and optimization method. The analytical method multiplies the inverse of a series of transformation matrices on the left side of each equation, then examines the elements on the right side of the equation, finds those that are zero or constant, and makes these elements equal to the elements at the corresponding positions on the left side to produce a valid trigonometric equation, and then solve the trigonometric equation. The geometric method first analyzes the ...
