This paper presents a mechanism for wheelchair transformation from two-wheeled upright position to fourwheeled position using a modular fuzzy logic control (MFC) approach. A wheelchair model that can be operated in fourwheeled and two-wheeled modes has been developed within the Visual Nastran environment and integrated with Simulink for control purposes. A multi-input multi-output modular fuzzy logic control configuration is designed and implemented on the wheelchair model. To improve the system performance, an input shaping technique is augmented inside the feedback loop. It is shown that the shaped signals have improved the system performance with promising results.
