Abstract

The invention discloses a flap rudder transmission device stepless adjustable in rotation angle ratio and a control method of the device. The transmission device comprises a metal transmission belt, adriving wheel group, a driven wheel group, a driving wheel hydraulic oil cylinder, a driven wheel hydraulic oil cylinder, a hydraulic pump, a hydraulic control valve and an ECU control unit. The equivalent wheel diameters of the driving wheel group and driven wheel group can be controlled through the hydraulic control valve, continuous change from the minimum degree to the maximum degree is achieved, and therefore the rotation angle ratios of a main rudder shaft provided with the driving wheel group and a wing rudder shaft provided with the driven wheel group can be continuously changed. Controllers are developed on the basis of an annealing immune fuzzy PID hierarchical control strategy, wherein the upper-layer controller outputs a main rudder angle value and a rotation angle ratio, thelower-layer controller controls the hydraulic control valve and a driving motor, and a flap can be adjusted online in real time during navigation steering of a ship in order to meet the requirements of ship maneuvering. According to the flap rudder transmission device, a gear set with a fixed rotation angle ratio is replaced with a gear set with a changeable rotation angle ratio, and stepless adjustment of the rotation angle ratio is achieved by combining with a control strategy, so that the flap rudder transmission device is easy to control.

Description

technical field [0001] The invention relates to a steering device and a control method of a ship, in particular to a flap rudder transmission device with steplessly adjustable rotation angle ratio and a control method thereof. Background technique [0002] In ship attitude control, heading control is mainly realized through steering movement, which requires the rudder to convert the forward thrust into the lateral force of ship motion as much as possible, that is, to generate as large a steering moment as possible. The flap rudder is to divide the rudder into two parts, the main rudder and the wing rudder according to a certain ratio. Through the transmission device, an included angle is formed between the main rudder and the wing rudder, which is actually to change the streamlined rudder into a camber the rudder. For the flap rudders currently used in engineering, gears, guide rod transmissions, hinges and other transmission methods are often used between the main rudder a...
