In recent years, the system parameter identification attracts attention of scholars and engineers, as the system control precision can be improved with it. In this paper, we take advantage of Hopfield neural network to identify the system parameters. Firstly, a kind of self balancing vehicle dynamic model is proposed. Secondly, the subsystem of the self balancing vehicle is analyzed in the form of...
This paper describes a dynamics model of a underwater glide vehicle. And a accurate model for calculating fluid dynamics of glide hydrofoil is also incorporated into the simulation. The model is used to simulate the glide motion of the underwater glide vehicle which is propelled and controlled through changing the gravity and location of gravity. The simulation results indicate that the underwater...
Control of UUV is performed in various methods. he fuzzy controller in a noisy environment had a significantly better performance compared by PID controller. This paper built the appropriate motion math model for the UUV the model for UUV's fuzzy control. Than the UUV which controlled by PID controller and controlled by the fuzzy controller are simulated. The results shows that the UUV can be steadily...
The ocean current is a disturb force when the autonomous underwater vehicle (AUV) navigating in the sea, it can induce the position change of the dynamic positioning AUV, so it can effect the low velocity maneuvers of the torpedo-shaped long-distance AUV. The appropriate motion math model for the torpedo- shaped long-distance AUV was built and the model for AUV’s ocean current disturb force was built...
