A Variable Fill Fluid Coupling (VFFC)provides a way to control an engine fan without the stress that a mechanical gearbox can add, unfortunately VFFCs are very difficult to model mathematically. Because of this, a fuzzy controller for the VFFC is proposed. This controller will be validated and compared to a non-fuzzy solution via a MATLAB simulation. The simulation will allow for an easy comparison of different membership functions and defuzzification methods. The results from these simulations will show that a fuzzy controller can perform equivalently to a non-fuzzy controller. The results also suggest that through more refined tuning, a performance improvement over the non-fuzzy counter-part.
