Path-tracking control of a laser guided vehicle using fuzzy inference system

This paper presents fuzzy inference system to control path-tracking type laser guided vehicle (LGV). In most of the industries, many of LGVs are used because of the safety. LGV can make a virtual path because it can calculate its absolute position. LGV also calculates both the error distance (derailment value) from the virtual path and the error angle using the position of LGV. For accurate driving control of LGV, we proposed path-tracking control of a LGV using fuzzy inference system which considered both the error distance and the error angle. To verify the performance of proposed method, we designed and used the simulator for the experiments.
