Abstract: By adopting the orthogonal transformations provided by the generalized real Schur decomposition, it is shown that every nonclassical linear system in state space can be transformed into block ...

Abstract: In this paper, a multibody dynamic model is established to simulate the dynamics and control of moving web with its guiding system, where the term moving web is used to describe thin materials, ...

Abstract: Excessive torque and drag in the wellbore can result in the buckling and the failure of the drillstring. Accurate predicting torque and drag is important in drilling operations. Due to the nature of the drilling, determination ...
