The ship´s mathematic motion models of altering course to avoid collision based on the optimization of genetic algorithm

From the nonlinear ship maneuvering motion mathematical model and geometric plotting point of view, This paper optimizes the parameters of ship mathematic model by using genetic algorithm in the ship automatic steering nonlinear sliding mode control, establishes the ship´s mathematic motion models of altering course to avoid collision based on genetic algorithm, and be tested in the simulation platform by MATALB, the result is consistent with the practice for preventing collision at sea.
