摘要
相比于传统管道封堵设备,智能封堵器在安全性和效率上显示出优势。目前智能封堵器碍于速度精度控制差、能量利用率不高的现状,导致其无法完成远距离作业。基于此,文章设计了一种节能和速度跟踪的智能封堵器控制系统。首先,在传统的封堵器结构上增加了飞轮和蓄能器装置,以实现系统的能量转换与储能;其次,设计了一种基于模糊PID的控制器用以提高系统的速度追踪能力。研究结果表明,文中提出的控制策略在闭环系统上具有更高的能源效率和稳定性,即智能封堵器的电液控制系统既能满足节能的目的又能达到速度跟踪目标。
The Pipe Isolation Tool(PIT)demonstrates advantages in safety and efficiency compared with traditional plugging devices.However,its utilization in plugging operations is limited by demand of operation duration and precise velocity trajectory.In this paper,a PIT control system is designed for energy-saving and plugging part's 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 objectives are satisfied for the PIT.
