Embodiment Construction

[0032] In order to make the technical means realized by the present invention, the creative features, the effectiveness of achieving the purpose and solving the problem easy to understand, the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0033] refer to figure 1 , figure 2 and image 3 As shown, the present invention discloses a joint control method of an engineering ship based on a three-degree-of-freedom rocker, a controller and multiple propellers, the steps are

[0034] a), the operator manipulates the joystick according to the observed current ship position and speed, and uses the joystick as an analog signal input unit to send lateral thrust or longitudinal thrust or yaw torque commands to the controller: the lateral gain of the joystick represents Thrust requirements in the ship’s sway direction, the longitudinal gain of the rocker represents the thrust requirement in the ship’s surge direction...

Abstract

The invention discloses a multi-propeller joint control method of an engineering ship. The operator controls the rocker according to the current ship position and speed according to the demand, and uses the rocker as an analog signal input unit to send lateral thrust or longitudinal thrust or yaw moment. instructions to the controller; the controller converts the received analog signals to obtain the values ​​corresponding to the thrust and torque requirements; For the real-time solution of the optimal control problem, the controller converts the solution result into an analog signal and outputs it to each propeller, so as to achieve the purpose of synchronously controlling the direction and speed of the propeller. The present invention uses an optimization algorithm to solve the optimization control problem on the controller through a single-chip microcomputer, and the thrusters execute the instructions of the controller to quickly and flexibly control the attitude of the ship, reduce the requirements for operators, and control each thruster conveniently and efficiently at the same time.

Description

technical field [0001] The invention belongs to the technical field of ship thruster control, in particular to a multi-propeller joint control method of an engineering ship. Background technique [0002] On a traditional ship, it is usually equipped with a fixed propeller (with rudder) as a means of propulsion and manipulation. [0003] With the increasing variety of ship operating conditions, the requirements for ship operating attitude and maneuverability are getting higher and higher. Various new types of propellers appear in the propulsion configuration of ships, such as azimuth propellers, pod propellers, and transversely arranged channel propellers. [0004] The increased variety of thrusters means that boat operators have a better understanding of how each type of thruster works. [0005] At the same time, the increase in the number of propellers puts forward higher requirements for the coordinated operation of each propeller, and it is difficult to meet the actual ...
