This paper proposed a finite-time prescribed performance control scheme for underactuated autonomous underwater vehicles (AUVs) based on adaptive neural networks and a tan-type barrier Lyapunov function. Even in the presence of output constraints and environmental disturbances. the AUV can also precisely track the desired trajectory in a finite time. By introducing a tan-type barrier ... https://www.diegojavierfares.com/mega-price-Houston-Texans-NFL-Side-Stripe-Training-Shorts-p6850-top-buy/
