Study On Robust Control Strategy And Trajectory Characteristic Of Underwater Vehicle

In recent years,with the rapid development of modern science and technology,research on submarine-launched missile carrier is becoming a hot topic in modern warfare. Robust Control Strategy is a modrn control strategies in a controlled manner, this control allows underwater vehicle control system to meet performance fast response. Compared with the traditional control strategy, which has a great advantage that it can consider the uncertainties,in the system so the system can achieve robustness and stability.In this paper, the study of the underwater vehicle is submarine-launched missile carrier .the main contents are:Firstly, hydrodynamic analysis, torque and the underwater vehicle by forces, then establish underwater vehicle model.Secondly, analysis the system uncertainty and to establish its model, using robust control methods to design the overload tracking system. and analysis of its results.Besides, to use the Particle Swarm Optimization to optimize the weighting function of robust control strategies, then to verify the validity of this method in selecting the weighting function and controller design problems.Finally, analysis the ballistic characteristics of carrier Underwater Vehicle stage and dynamic motion simulation and analysis level segment and turning its segment.From the perspective of engineering application in this paper, the depth underwater vehicle systems robust control strategy and design of the controller, and then analyze the ballistic characteristics of the carrier, which has a certain reference value for engineering practice.
