Design of the Family Intelligent Wheelchair Navigation System

We proposed an Intelligent navigation control scheme for intelligent wheelchair which is used at home. It used to control the action of wheelchair, such as start-up, straight line driving, turning and stopping. We study on laser sensors based localization of intelligent wheelchair, and using gyroscope to measure the roll angle. For straight line driving and turning, the use of three closed-loop control system to control the action of wheelchair. It ensured the accuracy of straight line driving and turning. Then closed-loop transfer function are obtained, then the mathematical model are set up. We present a modeling description of block diagram of control system through MATLAB, and we analysed the feasibility of the control system.
