Application of Fuzzy Control Theory in Obstacle Avoidance Simulation of Intelligent Wheelchair

This paper introduces application of the fuzzy control theory in obstacle avoidance simulation of intelligent wheelchair. Aiming at the path planning problem of intelligent wheelchair, with fuzzy theory, based on the information acquired from ultrasonic sensors that installed in the intelligent wheelchair, processed by fuzzy logic algorithm, then the fuzzy controller of fuzzy control theory was constructed in Matlab, so intelligent wheelchair obstacle avoidance simulation was conducted. The results show that this method can effectively avoid the obstacles, realize the continuous movement of intelligent wheelchair.
