| 针对典型航空发动机阀控不对称作动筒的结构在带负载工况下的应用和理论分析情况，讨论了作动筒正、反向负载对
伺服作动控制的影响，提出了1 种阀控不对称作动筒的伺服控制系统建模与分析方法。将该方法在项目案例上的分析结果与实际
项目试验数据进行对比，结果表明：该方法切实可靠，模型置信度高，对实际应用具有指导意义。同时，为了使作动筒往返控制效果
一致，作动筒负载方向应设计为反向负载，负载力大小应设计在FL0 附近。 |

| In view of the application and theoretical analysis of the structure of a typical aeroengine valve-controlled asymmetrical
actuator cylinder under load condition，the influence of the forward and reverse loads of the actuator cylinder on servo actuation control was
discussed. A method for modeling and analyzing servo control system of valve-controlled asymmetrical actuator cylinder was presented . The
analysis results of this method in the project case were compared with the actual project test data. The results show that the method is
practical and reliable，and the confidence of the model is high. It has guiding significance for practical application. At the same time，in
order to make the control effect of actuator cylinder round trip consistent，the direction of load should be designed as reverse load，and the
load force should be designed in the vicinity of FL0. |
