Simulated Analysis of Error in Submarine Horizontal Plane Linear and Non-Linear Manoeuvre Movement Model

Submarine horizontal manoeuvre movement model is the foundation of submarine horizontal manoeuvre movement simulation,and the fitness of model can affect the accuracy and real-time of simulation.Taking a certain submarine as the research object,this paper gave the simulation programme and some data,and after comparing with the real test data and analyzing the simulated errors in the two models,this paper found that the influence of non-linear part on submarine horizontal manoeuvre movement model is prominent,and the simulated error of non-linear model is much less than linear model.Compared with the linear model,the non-linear model is more valuable.
