摘要
为了减少液压系统建模时的推导过程,利用键图法和电路网络法2种建模方法的优点为液压系统建模.先将液压系统绘制成键图,再将该键图转换成等效的电路图,然后由电路网络法直接写出该系统的传递函数的数学模型.最后给出了所建的液压系统模型的鲁棒控制,仿真结果良好,控制的鲁棒性较强.
In order to simplify the modeling procedure of a hydraulic system, we take advantages of bond graph and circuit network. First, the hydraulic system was drawn into a bond graph, and the bond graph was transformed into its equivalent circuit diagram. Then, the transfer function of the system could be directly written with circuit net- work modeling method. Finally, the robust control for the proposed model was given. Simulation results showed that the proposed model is effective and has strong robustness.
