A Design of fuzzy controller for Autonomous Navigation of Unmanned Vehicle

The design approach is proposed for fuzzy logic controller for autonomous navigation of a vehicle in an obstacle filled environment. The proposed fuzzy controller is composed obstacle avoidance layer, orientation control layer, passage detection module. Here the fuzzy controller for obstacle avoidance is proposed. It provides a model for multiple sensor input fusion and it is composed of eight individual controllers, each calculating a collision possibility in different directions of movement. By calculating value of collision possibility main controller that performs real-time collision avoidance. The operating frequency & logic cells requirements for different implementation techniques are find out. The designs have been carried out in the digital domain with VHDL using Altera Quartus-II software.
