| Summary: | —The paper describes the model of a two flexible joint
manipulator and the development of a nonlinear passivity
based control method for that model. For dynamic modeling,
the Euler-Language approach is selected to model flexible joint
manipulator. Since lightweight materials are employed in the
construction of manipulator, the assumption that negligible
link deformation no longer applies. A nonlinear passivitybased control method for rigid flexible joint as well as flexible
link is proposed here. The main idea of Passivity Based
Controller (PBC) is to use energy state of a system to provide
stabilization. The PBC is developed to achieve two goals: set
point regulation and trajectory tracking. The controller brings
the end point from unstable position to a certain stable
position. Beside that, the controller are developed to control
the position of there end-point in such a way that it tracks the
desired trajectory which are tested by simulations. |
