摘要
在建立变柔性负载实验台变频式电液力控制系统的数学模型的基础上,利用AMESim和Simulink建立系统仿真模型,并进行基于PID控制和模糊自适应PID控制的联合仿真。仿真结果表明:基于模糊自适应PID算法的变频式电液力控制系统改善了系统的响应,减小了超调量,可应用于工程实际。
Based on the mathematic model of variable frequency electro-hydraulic force control system with time varying flexible load,the simulation models were established in Simulink and AMESim.Simulation was carried out based on PID control and fuzzy adaptive PID control.The simulation results show that the electro-hydraulic servo force control system based on fuzzy adaptive PID algorithm has quick response and small overshoot.It can be used in practical project.
