Automation Control

With rapid developments in industry wide automation control systems, there have been numerous proposed design and control strategies as alternatives to conventional methods. This term paper deals with the same in the context of Automated Guided Vehicles (AGV’s) with a review of the current literature for proposed design improvements as well as trajectory control systems that can improve productivity and reduce conflicts compared to current methods. The results of these proposed methods are also compared in contrast to each other to obtain holistic view of the merits and demerits of the same. It is found that a fuzzy logic based PID control is a definite upgrade over conventional PID control systems and that the application of LIDAR and Camera based technologies can help enable free roaming AGV’s lending to increased robustness and flexibility. For a control system consisting of a single AGV and multiple processing stations, a genetic algorithm enhanced centralized fuzzy logic control system is the most optimal path planning algorithm whereas in the cases of multiple robots, a dynamic priority allocated free roaming AGVsystem with semi-decentralized control is found to be much more efficient at simultaneously solving paths and reducingconflicts with other robots in real time compared to the purely centralized systems.
