Embodiment 1

[0042]A wave glider adaptive floating body heading control method comprises the following steps:

[0043] (1) Set the length of the sliding time window;

[0044] (2) The dynamic data storage queue is set, the size of its storage space corresponds to the set sliding time window size, the data structure adopts the queue form, and the elements therein are initialized to 0;

[0045] (3) Judging that the current control system is in the rapid adjustment stage or the steady state adjustment stage, if it is the rapid adjustment stage, then enter step (4); if it is the steady state adjustment stage, then enter step (5);

[0046] (4) Insert a "0" element at the back end of the dynamic data storage queue, and delete an element at the front end of the dynamic data storage queue, and enter step (6);

[0047] (5) Insert the heading difference of the floating body and the submerged body at the back end of the dynamic data storage queue at the current moment, and delete an element at the fr...

Embodiment 2

[0056] combine figure 1 Explain the wave glider and its hardware structure. The wave glider is composed of a floating body 1, a submersible body 2 and an umbilical cord 3, and the floating body 1 and the submersible body 2 are connected through the umbilical cord 3. The steering gear 4 of the wave glider is installed on the submerged body 2. Through the rudder force of the rudder plate 5, the steering of the submerged body 2 can be directly controlled. The turning moment of the floating body 1 comes from the tension of the umbilical cord 3. The floating body 1 and the submerged body 2 are respectively A heading sensor is installed, and the heading sensor 6 installed on the floating body and the heading sensor 7 installed on the submerged body respectively measure the heading ψ of the floating body F and the submerged heading ψ G .

[0057] combine figure 2 Describe the establishment of the coordinate system. Only considering the motion of the wave glider on the horizonta...

Abstract

The invention discloses an adaptive floating body heading control method for a wave glider, and belongs to the technical field of motion control of an ocean aircraft. According to the invention, an expected heading of a submerged body is planned in real time by utilizing actual navigation data of the wave glider; by heading control on the submerged body, floating body heading control on the wave glider is indirectly implemented; a problem of an unstable control system caused by floating body heading response lag is solved; and a steady state error caused by environment interference can be eliminated, and the floating body heading control ability of the wave glider is effectively improved. The adaptive floating body heading control method for the wave glider is simple in structure and easyto implement, does not depend on an accurate mathematical model and has high adaptivity under the uncertainty outside environment interference.

Description

technical field [0001] The invention belongs to the technical field of marine aircraft motion control, and in particular relates to a method for controlling the heading of an adaptive floating body of a wave glider. Background technique [0002] The wave glider is a new type of unmanned ocean exploration platform, which uses the "floating body-umbilical cord-submersible" rigid-flexible mixed multi-body structure to directly convert ocean wave energy into its own forward power, while relying on the solar panels on the upper deck It can provide power for various electrical loads, can carry out long-term autonomous navigation on the vast ocean, and can also serve as a communication relay to exchange instructions and data with other types of detection platforms, providing new ideas for ocean observation technology and has a very broad development prospect. [0003] The steering system of the wave glider, that is, the steering gear and the rudder plate, are installed on the subm...
