中文摘要: 首先论述了混合动力装载机变频泵控转向液压系统的基本结构。之后对IPMSM数学模型进行精确反馈线性化，并结合H∞混合灵敏度控制方法，采用改进的量子行为粒子群算法对混合灵敏度问题加权函数的系数进行优化；依据优化后的加权函数，通过求解LMI得出IPMSM的鲁棒控制器。最后对装载机实际V形铲装作业时转向系统的负载状况进行仿真研究，基于实地铲装作业测试数据的仿真结果表明：所设计的控制器可以使IPMSM驱动定量泵输出适量的液压油，以满足装载机正常转向时对油液的需求；同时，与阀控及一般泵控转向系统相比，变频泵控转向系统更加节能。
Abstract:Firstly, the basic structure of variable frequency pump-control steering hydraulic system of a hybrid wheel loader was illustrated. Secondly, the exact linearization of IPMSM system was realized by state feedback based on differential geometry, and combined with H∞ control method as well as improved quantum-behaved particle swarm optimization , the robust controller of IPMSM was solved. Simulation results show that the variable frequency pump-control system meets requirements of load conditions of wheel loader’s steering system, and its energy efficiency is higher than valve-control steering hydraulic system and normal variable displacement pump system.
