针对矢量喷管位置伺服系统在实际运行过程中容易受到系统外部扰动导致参数不确定的问题,设计了基于软件接口的机电液系统联合仿真与控制方案,通过SolidWorks、ANSYS、ADAMS、EASY5和Simulink之间数据交换分别建立了矢量喷管伺服机构刚柔耦合动力学模型、液压系统动态模型和滑模控制器,并通过接口实现了矢量喷管位置伺服系统仿真模型的集成。仿真结果证明:采用自适应模糊滑模控制器有效克服了矢量喷管位置伺服系统参数不确定和非线性的影响,实现了对矢量喷管伺服机构的高精度控制。

Co-simulation and Control Scheme of Vectoring Nozzle Servo Mechanism

In view of the problems that vectoring nozzle servo system is vulnerable to external distance in the process of actual operation and then the parameter becomes uncertain, the co-simulation and control method based on software interface is proposed in this paper. The rigid-flexible-coupling dynamic model of vectoring nozzle servo mechanism, hydraulic system dynamic model and the sliding mode controller are established respectively through data exchange of SolidWorks, ANSYS, ADAMS, EASY5 and Simulink, and then integration of simulation models for vectoring nozzle servo system is realized by software interfaces. The simulation results show that adaptive fuzzy sliding mode control strategy could overcome the effect of uncertainty and nonlinearity on system parameter and implement the high accuracy of vectoring nozzle servo mechanism.
