Abstract :
The decision-making system of AUV is very important for the safe and autonomous voyage of AUV during the long range travel. A kind of AUV decision-making system based on multi-thread technology under QNX is implemented in this paper. Hybrid system and supervisory control theory are introduced. A synchronization module combined with QNX message-passing is designed to realize the communication and synchronization between threads in the AUV decision-making software. Finally, we validate the software in a semi-physical computer simulation system.
