摘要
本文对电液比例变量泵控马达系统进行了研究,对实际工程很有指导意义。本文建立了泵控马达系统的数学模型,并对控制系统进行了设计。应用了PID控制,使系统得到了令人满意的控制性能。本文还使用了MATLAB软件来辅助控制系统研究,使控制系统的设计难度大为降低。
This paper puts great emphases on the study of electro-hydraulic proportional variable displacement pump control motor system,which has great significance to the practical engineering.Then it sets up the complete mathematical model of dynamic characteristics for the whole hydraulic system, and brings forword a control method of the system, the PID control strategy. The PID control strategy is feasible on the control system. It is very easy to carry the model of the control system on emulation in MATLAB.
