摘　　要：针对混合动力技术的挖掘机回转控制系统制动超调等问题,建立挖掘机回转装置模型,采用模糊PID控制算法,通过Matlab/AMESim联合仿真软件平台进行验证,并基于矿用混合动力挖掘机进行实测。结果表明,所采用的控制策略能够满足其回转制动的性能要求,并具有良好的节能效果,分析结果为促进混动挖掘机回转作业系统的设计与评价提供了一定的借鉴意义。For the braking overshoot of excavator slewing control system based on hybrid power technology,a model of excavator slewing device is created.The fuzzy PID control algorithm is adopted,and MATLAB/AMESim co-simulation software platform is employed to verify the model.In addition,actual test is carried out on the basis of hybrid power excavator for mine.The results show that the adopted control system can meet the performance requirements of slewing brake and have a good energysaving effect.The analysis results provide some reference for improving the design and the evaluation of slewing operation system for hybrid excavator.
