Electric Wheelchair Controller Based on Parameter Self-Adjusting Fuzzy PID

According to the wheelchair control particularity for requirements, this paper proposes a parameters self-adjusting fuzzy PID control strategy in accordance with wheelchair speed deviation and changes in the rate of deviation which is applied to DC motor speed control system to achieve optimal control for the wheelchair. At the same time, implement control system simulation though MATLAB toolboxes. It is proved that the system possesses good robustness, zero overshoot, smooth speed control, anti-load disturbance etc,which meet the control requirements for the electric wheelchair.
