However, its utilization in plugging operations is limited by demand of operation dura- tion and precise velocity trajectory. In this paper, a PIT control system is designed for energy-saving and plug- ging parts velocity tracking of the PIT. To achieve energy recovery and velocity tracking control, a flywheel and an accumulator are used for energy transformation and storage. A fuzzy PID controller is proposed to improve the ability of the desired velocity trajectory. The proposed control strategy is more energy efficient and more internal stable dynamics on the closed-loop system. The results verify that both energy-saving and velocity tracking ob- jectives are satisfied for the PIT.
