About this Research Topic
Crane systems such as overhead cranes, tower cranes, boom cranes, and so forth; have received abundant attention from the modern industrial field. Generally speaking, since crane systems have many advantages such as high flexibility, simple structure, low cost and the ability to operate in large workspaces; different crane systems are widely used in various industrial scenarios. However, due to the fact that the transported cargo is linked to the trolley or the jib by a rope, crane systems are all underactuated systems; which have more to-be-controlled degrees of freedom (DOFs) than independent control inputs. The underactuated property increases the control difficulty of crane systems and in past decades, the problem of controlling crane systems is regarded as one of the most challenging topics in the nonlinear control field.
Most industrial crane systems are operated manually, which brings many problems, including low working efficiency, poor positioning accuracy and high operation difficulty. To avoid these problems and promote the automation level for crane systems, it is urgently needed to design effective control methods for different kinds of crane systems. By carefully analyzing the nonlinearity, high coupling, and underactuated characteristics, we gain an insight into the effectiveness of current control methods and an understanding of how control research may positively impact crane system control.
This Research Topic aims to provide comprehensive insight into the latest investigations exploring different kinds of crane systems and promote the control research for similar mechanical systems.
We welcome the research on control of crane systems that could effectively improve the performance by open or closed-loop control schemes. Potential topics include, but are not limited to:
• Designing and modeling of practical crane systems
• Trajectory planning for crane systems
• Tracking control for crane systems
• Methods to tackle disturbances for crane systems
• Methods to tackle system uncertainties for crane systems
• Intelligent control for crane systems
• Emergency braking methods for crane systems
• Methods to tackle obstacle avoidance problem for crane systems
• Constraint control for crane systems
