An application mode for high-precision path planning control application of automated guided vehicle (AGV) with a large space is proposed based on the combining of the workshop measurement positioning system (wMPS) and the fuzzy control algorithm. AGV path is planned in advance, and the real-time position and pose of AGV is accurately measured by wMPS, and the real-time forward and rotational speed parameters of AGV are output by the fuzzy control algorithm. Simulation and experimental results show that the positioning accuracy of AGV is better than 2.5 mm, which can ensure dynamic navigation and positioning accuracy of AGV.
