Embodiment 1

[0034] Embodiment 1 provided by the present invention is an embodiment of a compensation method based on an surf compensating apparatus according to the present invention, such as figure 1 The flow diagram of an embodiment of a compensation method based on an surf compensation apparatus is shown in the present invention. figure 1 It can be seen that the method includes:

[0035] Step 1, establish a platform Pose Prediction model PL under the action of the wave predict Predictive model PU after co-waited compensation predict It is predicted to obtain a platform predictive position and moving platform prediction position.

[0036] During the specific operation, you will also need to obtain the initial current positional PL of the surf compensator platform and the moving platform. 0 PU 0 .

[0037] Preferably, the establishment of platform bit posture prediction model PL predictFor a function, PL related to the positional PL of the platform observed in this waves predict = F l (PL). ...

Abstract

The invention relates to a compensation method based on a sea wave compensation device, comprising: establishing a fixed platform pose prediction model under the action of sea waves and a moving platform pose prediction model after sea wave compensation, respectively predicting and obtaining the fixed platform predicted pose and the moving platform Predicted pose; determine the predicted target pose of the moving platform relative to the fixed platform according to the predicted pose of the fixed platform and the predicted pose of the moving platform, and determine the expected position of the drive of the compensation device according to the predicted target pose; Determine the expected input of the compensation device; by modeling the sloshing of the fixed platform under the influence of sea waves, and modeling the moving platform under the action of compensation, effective double feed-forward control is realized and the adjustment ability of the system is increased; applicable It is suitable for various sea wave compensation platforms including this type of sea wave compensation device; taking the working space of the compensation system into consideration, the comprehensive compensation ability of the system for relatively large sea waves is guaranteed.

Description

Technical field [0001] The present invention relates to the field of instrument science, and more particularly to a compensation method and system based on an surf compensation device. Background technique [0002] The marine resources are rich, and it is an important trade channel. However, the influence of the marine factors such as wind, waves, flow, and tide, sea ships or even sea platforms can not maintain balance, and precision instrument equipment cannot be stabilized, and the time, safety and quality of maritime operation cannot be guaranteed. It is necessary to use a compensator based on an surf compensation device to provide a stable working environment for the installation and maintenance of offshore platforms, ship equipment and materials transportation, placement, maintenance, and various precision instruments. [0003] The wave compensation points are mainly compensated for active wave compensation and passive waves. Active wave compensation requires a variety of se...
