Path Tracking Control Approach and Processing Lumped Disturbances for AGV in Recent Years: an Overview

AGV (Automated Guided Vehicles) - has been widely applied to many different fields for the purpose of goods transportation from the receipted to the delivery place. AGVs are particularly useful in situations where the repetitive movement of action over a predetermined distance is required. Their performance greatly affects the performance of the distribution system. Currently, a lot of research on AGV has been done. But in this review paper, we directly focus on the problem of path tracking control and lumped disturbance handling during the movement of AGV. The control methods are mentioned with the analysis of advantages, disadvantages, their development orientation, and application in the future; such as PID, sliding method control, Fuzzy logic systems combining with neural networks, model predictive control, Backstepping techniques, and control methods combining extended state observers to estimate and compensate for lumped disturbances. This research problem will provide some general information about over 30 articles in recent years to help readers understand and have an overview of the problem of AGV control when using different control methods.
