摘　　要：首先对具有非对称阀的非对称动力机构进行建模,然后对实际工况中非对称动力机构存在的外力干扰、非对称动力机构本身存在的正反向位移不一致及换向瞬间的压力跃变问题采取相应的控制策略,并对其进行仿真研究,仿真结果对解决非对称动力机构的伺服控制问题具有参考价值。The model of the asymmetry drive mechanism with asymmetry valve was set up. According to the real system with external force interference and its own asymmetry displacement and the sudden pressure jump, some control methods were used to solve these questions. The simulation result of asymmetry drive mechanism system is very useful to solve the servo control questions.
