Description

technical field [0001] The invention belongs to the technical field of ship steering and motion control, and in particular relates to a steering data recording circuit. Background technique [0002] The optimal design of steering control depends to a large extent on the mastery of the ship's motion model. Obtaining actual ship steering and motion data is the key to the further development of steering control technology; for a long time, due to the lack of actual ship steering and motion data, research on steering control methods by domestic research units mostly stays at the level of assumptions and simulations , the usability of the research results is not very strong; in order to further study the steering control system, it is very important to obtain real ship data. Contents of the invention [0003] The present invention aims at the above problems, makes up for the deficiencies in the prior art, and provides a steering data recording circuit; the present invention so...
