摘要
在分析旋转作动筒数学模型的基础上,为了更准确地进行旋转作动筒作动性能分析和算法验证,设计了一种考虑燃油压力影响的旋转作动筒控制系统模型。在Matlab/Simulink中,建立独立的功能模块,包括控制器模块、电液伺服阀模块和旋转作动筒模块等,然后再将这些功能模块进行有机整合,组建成旋转作动筒伺服控制系统模型[1]。为保证仿真的快速性和有效性,控制器采用PI算法,电液伺服阀开口面积与电流的关系采用一维查表方式,旋转作动筒根据实际物理结构并考虑开、关两状态下压差的不同建模。仿真结果表明,该方法可靠有效,为旋转作动筒控制系统的设计及试验提供了新思路。
On the basis of analyzing the rotating actuator cylinder model,in order to perform the performance analysis and algorithm verification of rotary actuator more accurately,a control system model of rotary actuator considering the influence of fuel pressure was designed.In Matlab/Simulink,build dependent functional modules,including the controller model,the electro-hydraulic servo valve model,rotating actuator cylinder model,etc.,and then integrate the functional modules,build the model of rotary actuator cylinder servo control system.In order to ensure the quickness and effectiveness of simulation,the model adopts PI controller,the open area of electro-hydraulic servo valve following current adopts one-dimensional look-up table,the model of rotary actuator cylinder designs as the actual physical structure,and considers the two kinds of differential pressure for opening and closing.The simulation results prove the effectiveness of the proposed method,and a new way of thinking for rotary actuator cylinder control system design and test is provided.
