TitleA unifying framework for the control of robotics systems
Journal/Conference/Book TitleIEEE International Conference on Intelligent Robots and Systems (IROS 2005)
AbstractRecently, [1] suggested to derive tracking controllers for mechanical systems using a generalization of Gauss principle of least constraint. This method al-lows us to reformulate control problems as a special class of optimal control. We take this line of reasoning one step further and demonstrate that well-known and also several novel nonlinear robot control laws can be derived from this generic methodology. We show experimental verifications on a Sar-cos Master Arm robot for some of the the derived controllers.We believe that the suggested approach offers a promising unification and simplification of nonlinear control law design for robots obeying rigid body dynamics equa-tions, both with or without external constraints, with over-actuation or under-actuation, as well as open-chain and closed-chain kinematics.
