Study of Refueling System of the Electric Wheel Truck of Mine Based on MRAC

以矿山电动轮汽车润滑油加油系统为研究对象,本文提出了一种基于Liapunov稳定性理论的模型参考自适应控制(MRAC)方法。分析了该加油系统的结构特点,建立对应数学仿真模型,再利用超稳定理论推导出加油系统自适应控制律,利用Matlab/Simulink对该数学模型进行仿真。模型仿真结果说明,该系统具有较高的稳态精度和较强的鲁棒性。

This paper presents a method of MRAC basing on Liapunov stability theory model by taking mine electric wheel automotive lubricants refueling system as the research object.And then the structure characteristic of this refueling system is analyzed,the mathematics model of the object is given,which is the basis for the derivation of the object adaptive laws.Matlab/Simulink is used to achieve simulation model for this system.The simulation results indicate that this system has higher steady-state accuracy and better robustness.
