Integration of a PID Control System for a Mobile System for Manufacturing Task on Continuous Conveyor

摘要

In this paper, we will introduce a new concept to reduce the non value added process in the manufacturing industry. This concept is based on the combination of transportation and machining tasks with mobile robots. The reason behind this concept is to reduce the waste of production time, cost and effort. To realize this concept, a demonstration system has been built. The first step to accomplish this system is to synchronize an automated guided vehicle (AGV) to a moving object. The position data of the AGV and the moving object are collected by using an optic measurement system and used to control the movement of the AGV. An external control system including a Proportional–Integral–Derivative (PID) controller has been built to control the AGV. Experimental validation was performed using an AGV and an optical measurement system for the proposed control system. The results show that the accuracy of the optimized control system has been improved in comparison with the control system without the use of the PID controller.
