为了稳定准确控制风帆转角位置,根据所设计的风帆驱动控制液压系统原理,提出风帆转角/速度复合控制方案。利用AMESim-MATLAB/Simulink软件建立风帆转角/速度复合控制联合仿真模型,并进行了联合仿真及实验研究。结果表明:采用复合控制可以克服常规控制中出现的压力波动及启停时的液压冲击;在不同转角速度及不同风力负载条件下,风帆均能按照规划的速度及位移进行转动,体现了复合控制的有效性和可靠性,可以为风帆助航船的风帆控制提供技术支持。 相似文献

A 6-axis motion simulator has been developed, in order to regenerate UGV (unmanned ground vehicle) motion and to test the
stabilization system of the mobile surveillance robot that is mounted on the UGV. For developing the 6-axis motion simulator,
a simulation-based design procedure was introduced. The 3D geometric model of the motion simulator was created by using 3D
CAD modeler ProE. The multibody dynamics model of the motion simulator has also been created by using the general purpose
dynamic analysis program ADAMS to validate the design of the motion simulator. Dynamics and control co-simulation model for
the motion simulator has been also established for control performance analyses. Actual hardware of the motion simulator has
been fabricated based on the proposed simulation based design. Hardware test of the motion simulator has been tried to validate
the design.

The driving stability of silo vehicles is significantly affected by the type of cargo that is transported and the design of
the tank. Cargo motion can have both beneficial and negative aspects in terms of driving stability and braking performance.
Neglecting the influence of the dynamically moving cargo in driving simulations of silo vehicles leads to significant errors
in the simulation results. We propose a new method for the dynamic simulation of silo vehicles carrying granulates. The method
couples Lagrangian particle methods, such as the discrete element method, and multibody systems methods using co-simulations.
We demonstrate the capability of the new approach by providing simulation results of two benchmark maneuvers.
