This paper deals with an underwater compressed air energy storage system. The power conversion chain is composed of a PWM-VSI-PMSM driving an underwater compression system. The excess energy is stored in form of compressed air in a tank located on the seabed. A multi-physic dynamical model of the power conversion chain is established. Considering conversion efficiency performances and system operating constraints, a control strategy management is developed. It consists in constraining the pump operating at the best efficiency point. From these considerations, a predicted speed profile is generated. The mechanical equation is identified as a first order system with a variable time parameter. To ensure the speed tracking, a RST controller is synthetized.
