“…The multibody dynamic equations of the triple pendulum system form a system of differential-algebraic dynamic equations that are analytically derived by using the RPCF-EP and the NACF. Subsequently, the Robust Generalized Coordinate Partitioning (RGCP) method is used for stabilizing constraint drift of the triple pendulum system as well as to enforce the kinematic constraints at both the position and velocity levels [60,61]. The constraint tolerance used in the Newton-Raphson (NR) numerical procedure implemented in the RGCP algorithm is equal to ε = 10 −9 .…”

“…This way of solving the problem can arise some numerical difficulties and efficiency, as it has been addressed in the thematic literature [32,80,91]. Nevertheless, the proposed approach is quite efficiency from computational point of view, because for the simulations performed within the goals of the present work, in general, no more the 2 iterations are needed to obtained a good convergence of the method.…”

“…It must be highlighted that the coordinate partitioning methods are effective and very useful [83][84][85] and a good number of investigations haven been carried out on the establishment of the sets of independent and dependent coordinates. In fact, over the last few decades, several approaches that allows for the selection of the independent set of coordinates have been proposed [86][87][88][89][90][91]. Recently, Carpinelli et al [92] studied the problem of the accuracy and efficiency of the implicit Euler approach when switching from dependent to independent coordinates.…”
