摘　　要：重载多缸同步举升控制系统在举升过程中,存在摩擦、元件泄漏、非线性以及各通道的互相作用,给举升系统的高精度同步控制带来了巨大挑战。针对此问题,建立同步举升控制系统的数学模型,应用模糊自适应整定PID控制策略,借助AMESim与Simulink软件搭建同步举升仿真平台对该举升系统进行仿真试验,并通过试验验证了电液比例同步举升系统及控制策略的合理性。试验结果表明:该控制算法能够实现重载多缸同步举升控制系统的高同步精度及稳定性的要求。The heavy-duty multi-cylinder synchronous lifting control system faces a great challenge in high-accuracy synchronous control of the lifting system due to friction,component leakage,nonlinearity and interaction of each channel during the lifting process.To address this issue,a mathematical model of the synchronous lifting control system is established,a fuzzy adaptive PID control strategy is applied,a synchronous lifting simulation platform is constructed with the help of software AMESim and Simulink to carry out simulation tests of the lifting system,and the reasonableness of the electro-hydraulic proportional synchronous lifting system and the control strategy is verified through tests.The test results show that the control algorithm can achieve the requirements of high synchronization accuracy and stability of the heavy-duty multi-cylinder synchronous lifting control system.
