Overhead cranes with double-pendulum effect seem more practical than those single-pendulum effect. However, in this case, it is difficult to find an applicable controller for such systems. Hence, a linearized and decoupled overhead crane dynamic model derived by adopting disturbance observer modal analysis technique. The S-shaped trajectory planned solving algebraic equations, the stability of system confirmed Routh–Hurwitz theory. Experimental results simulations demonstrate effectiveness...
It is seen that when the hook mass larger than load or has distributed property, sway of crane system presents as double-pendulum effect. In this situation, two different natural frequencies so characteristic becomes more complex and greatly increases difficulty dynamic performance analysis controller design. Moreover, rope length changes significantly affect stability control system. order to solve aforementioned problems, linear dynamics a two-dimensional overhead with effect derived based...
When the hook mass is larger than load or has distributed property, sway of crane system presents as double-pendulum effect. In this situation, two different natural frequencies so that characteristic becomes more complex and greatly increases difficulty dynamic performance analysis controller design. order to solve aforementioned problems, linear dynamics a 2-D overhead with effect derived based on disturbance observer, decoupled for design by modal analysis. Next, an S-shaped curve which...
In this work, a trajectory generation method is proposed to meet the functions of boom positioning, load elimination and obstacle avoidance for limited working space motion constraints rotary crane. The key point paper that when position static known, depth camera can obtain random starting three-dimensional coordinates ending coordinates, then an be automatically generated tracked by controller.
This paper deals with robust control problems for double-pendulum overhead cranes. For this reason, a linearized and decoupled crane dynamic model is derived by adopting disturbance observer modal analysis technology. Next, linear feedback controller, whose gains are obtained via LMI optimization method, proposed. Finally, numerical simulations validate that the proposed method has superior performance.
Facing the energy crisis, Flywheel Energy Storage System (FESS), representing physical storage technology, has great application prospects in market owing to its high conversion efficiency. In practical applications, structure of Array Systems (FESAS) is mostly used. Although traditional allocation strategies for arrays are straightforward and easy implement, they often fall short optimal allocation. This paper proposes utilization Particle Swarm Optimization (PSO) algorithm power command...
