Research Abstract |
This study was aimed at developing a high precision and reduced order model for the extremely flexible body undergoing large rotation and large deformation in order to design a controller for such a highly nonlinear system. As the result, the proposed reduced order model which uses a kind of component mode synthesis method enables to reduce the dimension size of the system matrix of flexible body and is verified to keep the numerical accuracy. Moreover it is also verified the present model can be applicable to design a controller of the mobile robot with extremely flexible link which is similar to floor gymnastics by numerical simulation.
