Design of a low power control system of an underwater glider

This paper mainly discusses the philosophy of designing a low power control system of our autonomous underwater glider. The control system structure and the reasons of selecting ARM processor are given. In order to control the system power consumption, the vehicle needs a periodical operation mode. Under the mode, a estimation of energy consumption rate is conducted and then we calculate the distance the vehicle can reach with one charge before a voyage. At last, a selection of the operating system is presented
