Abstract
In case of flooding, the underwater flight vehicle (UFV) executes the emergency blowing by blowing ballast tanks off using high pressure air (HPA). However, the conventional blow-off method lets the body on the surface after blowing despite slight flooding. This results in the unnecessary mission failure or body exposure. Therefore, it is necessary to keep the body at the near surface by the blowing control while reducing the overshoot depth. To solve this problem, a blowing control algorithm using the expert knowledge and the fuzzy basis function expansion (FBFE), is proposed. Simulation results for verifying the performance of the proposed algorithm show that the proposed algorithm effectively solves the problems in the UFV blowing control system.
