摘要
面向海底作业工况,设计针对海底重载无人车行走机构的变频调速液压系统,并建立其AMESim数值模型。通过仿真对PID(Proportion-Integration Differentiation)控制器的参数进行整定,并对其切换动态过程进行分析。结果表明,设计的变频调速液压系统具有良好的动态响应特性,该研究可为海底重载无人车行走机构液压系统的优化设计和控制策略研究提供理论依据。
A viable frequency speed regulation hydraulic system is designed for the walking mechanism of seafloor heavy duty unmanned vehicle based on the seafloor operating situation,and the AMESim numerical model of the system is established.The parameters of Proportion-Integration-Differentiation(PID)controller are tuned during simulation,and its dynamic switching process is analyzed.The result shows that the hydraulic system designed has excellent dynamic response characteristics.This study provides a theoretical basis for the design optimization of hydraulic system and control strategy investigation of the seafloor heavy duty unmanned vehicle's walking mechanism.
