Ship motion control simulation platform and ship motion control method

Abstract

The invention discloses a ship motion control simulation platform which comprises a control module, a driving module, an attitude measurement module, a position determination module and a power module. The driving module is used for controlling the forward movement and turn of a motion platform. The attitude measurement module and the position determination module are used for measuring the attitude and position data of the motion platform. The control module is provided with a track tracking algorithm and a deck motion model. The control module obtains the attitude and position information of the motion platform from the attitude measurement module and the position determination module and then carries out track tracking calculation, then a ship moves according to an expected path through the driving module according to a calculation result, and the deck movement of the ship in waves can be simulated at the same time. Further, the invention also discloses a ship motion control method. Through the platform or the method and an indirect control method of separating heading control and track control, the control parameter adjustment is simple, and a heading control and a track control algorithm can be modified separately.

Description

technical field [0001] The invention belongs to the technical field of ship motion control simulation, in particular to a ship motion control simulation platform and a ship motion control method. Background technique [0002] The movement of the ship on the sea will affect the landing accuracy of the aircraft. The attitude of the ship can be judged by pattern recognition, so as to choose the right time to land. In the study of aircraft landing, a ship motion simulation platform is essential. The design and simulation of the prototype system has a very wide application value, and can quickly verify the principle scheme of the design system. In order to test whether the design of the control system is reasonable and whether the control algorithm is effective, it is necessary to pass multiple water tests. Each experiment needs to synthesize the motion data of the ship, and then analyze and organize to obtain a comprehensive evaluation of the control performance, so as to comp...

Problems solved by technology

[0003] The computer simulation method is low in cost and simple, and is the most commonly used initial simulation method. It has good interactivity and can better simulate the movement of ships in sea waves. The accuracy of the sea state has a great relationship, so it can only be used as a preliminary means to verify various control methods

The real ship test has high reliability, but it is dangerous and costly, so it is generally used after the control method is verified by computer simulation and the feasibility is basically confirmed.

Compared with the first two methods, the hardware-in-the-loop platform simulation has higher reliability, low cost and safety, and is widely used. However, there are few ship motion simulation platforms at present, and the control algorithm is complex, parameter adjustment is difficult, and the algorithm can be transplanted. Sex is not high
