Fan Performance Curve Drawing Based on Configuration Software

Configuration software has been intensively applied in the monitoring system of the ventilator. Considering the importance of fan performance curve on fan operation, according to the principle of least squares fitting curve, the ventilator's performance curve can be drawn through the xy curve of the force control configuration software. Then， when we describe the ventilator's performance curve, the xy curve has high accuracy by comparing it with the MATLAB fitting curve.
