Heuristic Approach to Trajectory Planning of N-th Numerous Set of Automated Cranes

Today new requirements are put for optimization, synchronization and planning the transportation operations supported via n-th numerous set composed by automated cranes, including also their availability. The above needs is the subject of consideration in the paper, and solved based on heuristic approach. The method of i-th cranes operations planning, as well as time-optimal and non-collision moving trajectory of a payload shifted by crane is solved using searching graph algorithm based on heuristic function. The presented approach is possible to apply also to n-th numerous sets of automated cranes. The application of crane set control system was based on supervisory system (HMI/ SCADA system) equipped in user interface for implementing the heuristic knowledge about considered process used to aid decision-making process.

The Fuzzy Robust Anti-Sway Crane Control System

The paper presents the pole placement approach to solve problem of conventional, based of proportional-derivative controllers, as well as robust, based of fuzzy controller, anti-sway crane control. The methods of robust gain-scheduling crane control system and selecting minimal set of operating points were shown. The fuzzy robust controller, based of Takagi-Sugeno-Kang inference system, was presented, as well as results of experiments, carried out using laboratory model of an overhead traveling crane, were shown in the paper.

Pole Placement Approach to Crane Control Problem

The time and positioning accuracy of transportation operations realized by material handling systems are more and more significant problem in automated manufacturing processes, as well as the exploitation quality, safety and reliability, which can be met by implementing automation systems and improving control quality of material handling devices. The presented problem of anti-sway control system was solved using pole placement method employed to the time-discrete closed loop crane control system, which can be used in adaptive solutions. The proposed solution is based on the assumption, that crane nonlinear system is considered as a linear model with varying parameters.

The Application of a Neuro-Fuzzy Adaptive Crane Control System

The unconventional methods, mostly based on fuzzy logic, are often addressed to a problem of anti-sway crane control. The problem of practical application of those solutions is important owing to come the growing expectations for time and precision of transportation operations and exploitation quality of material handling devices. The paper presents the designing methods of an adaptive anti-sway crane control system based on the neuro-fuzzy controller, as well as the software and hardware equipments used to aid the programming realization the fuzzy control algorithm on a programmable logic controller (PLC). The proposed application of control system was tested on the laboratory model of an overhead traveling crane.

Effects of Improved Traffic Management on Sustainable Distributed Road Transportation Safety Based on Asian Experiences

Knowledge of the improved traffic management and its effect on road safety is an important component in the process of sustainable road network development. Having in mind that so many road traffic casualties occur, a key priority in transport policy is making highways as safe as possible. The mentioned objective is attained by means of sustainable safety. The paper focuses on sustainable road safety and his principles, based on selected Asian countries experiences. The knowledge base covers institutional responsibility of road safety, the development of a road safety action plan, raising awareness and understanding of road safety problems, road crash data systems, road safety education and training, traffic safety legislation, enforcement of traffic laws and monitoring and evaluation of the effectiveness of road safety activities. In order to improve road transportation safety an organized sustainable approach is needed via concentrated action of all of participants in the process of realizing the transport service such as: governments at all levels, those who are professionally engaged in transport and traffic engineering and road users themselves.
