基于Modelica语言的柔性结构振动控制仿真

柔性结构在快速定位过程中容易产生长时间的瞬态振动而影响定位速度和精确度,因此必须对其进行主动控制。然而,柔性结构振动控制的仿真一直存在难以建模的问题。该文为此提出一种基于Modelica语言的新的仿真途径。它具有建模工作量小、模型重用性好的特点。对一个空间梁型结构振动控制的仿真结果表明了该方法的有效性。

Vibration Control Simulation for Flexible Structures by Modelica

Flexible structures can have a long transient vibration when positioned quickly, which is harmful to their positioning speed and accurate tracking ability. However, it is usually difficult to simulate such a vibration and to test control schemes for it on computer due to tedious preparation work. This paper works out a new method to do that by the use of Modelica language. This method can reduce the modeling difficulties and make the model much more reusable. Simulation of a space frame shows the effectiveness of the new method.
