Overhead cranes with double-pendulum effect seem more practical than those single-pendulum effect. However, in this case, the dynamic performance analysis and controller design become difficult. Moreover, achieving both high-precision trajectory tracking load sway rejection is a significant issue for crane systems. For these purposes, nonlinear dynamics of an overhead derived design. Then, novel adaptive hierarchical sliding mode presented. Unlike traditional approach, proposed one can make...

Furthermore, uncertain parameters and external disturbances in crane system make it difficult for traditional control methods to obtain satisfactory performance. Hence, this paper an adaptive nonlinear based on dynamic model rotary crane. Unlike a method, proposed one does not need linearize design;...
To speed up the response and reduce chattering of a sliding mode control system, novel reaching law with two variable power terms is proposed, which makes system have fast approaching rate either far away from or close to surface. Moreover, an improved global terminal surface dynamic coefficients can make states arrive at equilibrium point along convergence rate. Furthermore, controller designed by employing proposed surface, quicken in both phase phase. Theoretical analysis shows that...
The Sliding Mode Observer (SMO) is widely used for the sensorless control of Permanent-Magnet Synchronous Motors (PMSMs) due to its simple structure and strong parameter robustness. However, traditional SMOs have a limited speed range suffer from chattering issues, which affect accuracy rotor position estimation. To address these problems, this paper proposes an Adaptive Super-Twisting SMO (AST-SMO) method. First, fast super-twisting function designed resolve step problem that occurs at...
