“…There is no friction at the suspension points. To build a nonlinear mathematical DAR model, let's use Lagrange equations of the second kind [8][9][10]. In our case, the coordinates are generalized q i and generalized speeds dq i /dt let's take the relative deviation angles of the stretched pendulum threads β and γ, and relative angular velocities of the links dβ/dt; dγ/dt.…”

“…Today, various systems are being developed that function to increase the safety of using tower cranes. The task of reducing the swinging of the load when the rope breaks has been studied in many works by scientists around the world [6,[8][9][10][11]. At the same time, it should be noted that in known studies, insufficient attention is paid to the dynamic description of failure modes of cable systems within the framework of establishing and solving differential-algebraic levels (hereinafter DAR), which determines the relevance of this work.…”

The object of research is the behavior of the load of the tower crane during the break of the sling. One of the most problematic areas is the safety of work and the prevention of emergency situations. Despite the presence of mandatory safety measures, during cargo transportation, one of the sling branches may be destroyed due to the presence of a dynamic component during the operation of the crane, or errors of the slinger when securing the cargo. Also, the presence of hidden internal or unnoticed defects in the sling construction itself cannot be ruled out. Also, one of the most problematic places is the chaotic fluctuations of the load, which negatively affect the stability of the crane and safety. The paper describes the case of the destruction of one of the branches of a two-rope sling during the transportation of a long product by a tower crane. The proposed method of cargo behavior analysis is based on the use of a dynamic description of cable system failure modes within the framework of setting and solving differential-algebraic equations. This makes it possible to more accurately describe the behavior of the cargo when the sling breaks. The obtained results show that the application of the proposed method makes it possible to bring the mathematical model of the two-link mathematical pendulum significantly closer to the actual mutual oscillations of the load during the sling break. This is due to the fact that the proposed method has a number of features, in particular, high sensitivity to changes in the behavior of the cargo and a quick reaction to a rope break. These results can be used in practice in the design and operation of tower cranes. Thanks to the application of the proposed method, it is possible to obtain accurate values of cargo behavior indicators and timely detection of a rope break. Compared to similar known methods, this method has such advantages as high efficiency, reliability and safety of operation.

“…For this reason, some meaningful results have been reported to deal with the control issues of overhead cranes with double-pendulum phenomena. [25][26][27][28] Especially, taking parameters uncertain and rope length variation into consideration, Lu et al design an adaptive control method, which achieves enhanced coupling between the trolley and the payload/hook. 26 Sun et al propose a new quasi-PID control approach for the control of overhead cranes with double-pendulum phenomena.…”

In this paper, a novel disturbance observer and a Lyapunov-based control approach are developed for the crane control. For existing works, the assumption on the disturbances is strong and the motivation of these methods is to reject disturbances by feedback control. To tackle these problems, this paper proposes a novel composite control strategy consisting of a nonlinear control method and a finite time disturbance observer. Specifically, first, based on the system dynamic equations, a disturbance estimator is put forward, which can exactly identify the unknown disturbances in finite time. Next, an elaborate Lyapunov function is constructed and a disturbance-compensation-based control approach is presented for the overhead crane system with double-pendulum dynamics. Then, rigorous theoretical analysis is given to prove that all of the states of the closed-loop system asymptotically converge to the origin. At last, simulation tests are included to verify the effectiveness and robustness of the proposed method.
