    Robust μ-synthesis controllers for suppressing stick-slip induced vibrations in oil well drill strings

    Stick-slip friction is a major cause of drill-string failure. This paper addresses the problem of suppressing stick-slip induced oscillations in oil well drill strings using a control design technique known as μ-...

    A generalised approach to point-to-point motion of multi-DOF parallel manipulators illustrated with TMPM

    The work presented in this paper describes a novel approach to the computation of the point-to-point motion of multi-degree-of-freedom parallel mechanisms. The common technique for solving for the inverse kine...
