基于液压变压器的装甲抢救车液压变幅系统分析

摘要

In order to improve the control performance of hydraulic luffing system in Armored Recovery Vehicle (ARV) , a new hydraulic luffing system in ARV based on hydraulic transformer is designed.Firstly, the working principle of the new system is analyzed.Then the mathematical model is built, and a control strategy based on fuzzy Proportion-Integral-Derivative (PID) is proposed for the speed control.The simulation results show that the new hydraulic luffing system in ARV has good control performance.%为了改善装甲抢救车液压变幅系统的控制性能, 设计了一种采用液压变压器控制变幅油缸的新型装甲抢救车液压变幅系统.分析了新系统的工作原理, 建立了系统的数学模型, 提出了采用模糊比例-积分-微分 (Proportion-Integral-Derivative, PID) 控制器进行速度控制的方法, 仿真结果表明:新型装甲抢救车液压变幅系统具有良好的控制性能.
