According to the AUV software fault repair problem in partially observable environment,a method based on Partially Observable Markov Decision Process(POMDP)model and micro-reboot mechanism for solving failure repair of AUV is presented. AUV software self-repairing POMDP model is established based on the characteristics of AUV hierarchical structure while can design multi-level micro-reboot repair method. With the help of repair strategy which based on the algorithm of Point Based Value Iteration(PBVI),the s...
