This paper proposes a fuzzy state feedback controller of depth control for unmanned underwater vehicle (UUV) to solve the communication time-delay problem resulting from application of the Network Control System (NCS). Firstly, we adopt T-S fuzzy reasoning method to express the vertical plane dynamics time-delay model of UUV. Secondly, by using Parallel Distributed Compensation(PDC) strategy, a state...
In order to achieve a smooth and non-overshoot performance for risk of striking the seabed in UUV bottom-sitting task, a soft landing guidance law is presented, which is inspired from the corresponding concept in aerospace science. The guidance law is a polynomial function with respect to time, and the desired vertical position, velocity and acceleration of UUV are determined. In particular, the necessary...
