本文针对液压挖掘机工作装置的变惯量和非线性特点，应用模糊控制理论，设计出了液压挖掘机工作装置的专家模糊控制器，计算机仿真和实时控制实验结果均表明，该模糊控制器对系统参数变化不敏感，具有很强的鲁棒性，从而较好地实现了液压挖掘机工作装置轨迹的自动控制
In this paper, according to the characteristics of variable inertia and non-linearity of working device of hydraulic excavator, fuzzy controller theory is applied to design the expert fuzzy controller of working device of hydraulic excavator. Computer simulation and real-time control experiment results show that this fuzzy controller is effective to system The parameter is not sensitive to changes, with strong robustness, so as to achieve the automatic control of hydraulic excavator work device trajectory
