Structure-Control Coupling Analysis
Three ways of the analysis and unique analysis technology of the company are introduced.
Summary
The company proposes primarily three ways of structural-control coupling analysis, which are described below.
1) Plug a structural model of matrix or transfer function formats into control analysis software such as MATLAB/Simulink
-> for mainly control design
2) Plug a control system of transfer function format into structural analysis software such as MSC Nastran
-> for mainly structural design
The approach is an application of MSC Nastran TF card.
3) Plug a control system and a structural model into kinematic mechanism analysis software such as Adams。
-> for Kinematic Mechanism + control design
| Strong Point | Week Point | |
|---|---|---|
| 1 | Easy to study control design | Hard to check on mode shapes |
| 2 |
Easy to output mode shapes Easy to study structural design |
No advanced control analysis capability |
| 3 |
Nonlinearity is included
|
Analysis load is high
|
There exists two ways of coupling analysis such as Adams and Simulink or Adams and MSC Nastran elastic element (Adams Flex).
