摘要
液压缸位置控制广泛应用于各类液压控制系统中,常采用电液伺服加载系统模拟其运动过程中的真实负载。该文首先建立电液比例位置控制和电液伺服加载系统的数学模型;然后对加载过程中产生的多余力进行分析,找出影响多余力的相关因素;最后采用"PID+速度前馈补偿"来改善加载系统的综合性能。
Hydraulic cylinder position control is widely used. Electro-hydraulic servo loading system is often used to simulate the real load. This article firstly build the mathematical model of electro-hydraulic proportional position and electro-hydraulic servo loading systems. Then analyze the surplus torque generated in loading process to find out the related factors influencing the surplus torque. Finally adopt ＂PID ＋ speed feed-forward compensation＂ to improve comprehensive performance of loading system.
