摘　　要：为了进一步提高汽车的节能效果,开发了一种以同步阀和电磁比例阀同时实现的液压动力底盘,设计了马达同步模糊PID自适应控制系统,利用AMESim开展仿真测试。研究结果表明:采用模糊PID调节后,系统经过1.75 s马达恢复为目标转速,之后进入稳定运行状态,实现同步直线行走功能。在同样负载条件下经模糊PID控制器调节后实现同步精度接近0控制状态,到1.75 s时二液压马达转速重新恢复至目标转速的稳定状态。该研究可以实现高精度同步控制以及具备快速响应能力的液压同步控制系统,为后续的参数优化奠定理论基础。In order to further improve the energy saving effect of excavator,a hydraulic power chassis realized by synchronous valve and electromagnetic proportional valve is developed,and the motor synchronous fuzzy PID adaptive control system is designed,and the simulation test is carried out by AMESim.The research results show that after fuzzy PID adjustment,the system is restored to the target speed by 1.75s motor,and then enters the stable running state to realize the synchronous linear walking function.Under the same load condition,the control state of synchronization accuracy is close to 0 after the fuzzy PID controller is adjusted,and the speed of the two hydraulic motor returns to the stable state of the target speed when it reaches 1.75s.The research can realize the hydraulic synchronous control system with high precision and rapid response ability,and lays a theoretical foundation for the subsequent parameter optimization.
