A Design of Fuzzy Controller for Autonomous Navigation of Unmanned Vehicle

This paper presents a design approach for fuzzy logic controller for autonomous navigation of a vehicle in an obstacle filled environment with obstacle avoidance layer, orientation control layer and passage detection module. It provides a model for multiple sensor input fusion and is composed of eight individual controllers. Each controller will calculate collision possibility in different directions of movement, according to which main controller would take action to avoid the collision. The designs have been carried out in the digital domain with VHDL using Altera Quartus-II Software.
