Approximate optimization for minimum torque ripple of three phase switched reluctance motor using response surface modeling

초록

The approximate optimization based on a response surface modeling has been applied to the optimum design for obtaining flat torque of switched reluctance motor, which has high fluctuating torque due to its inherent salient structure. In order to reduce the fluctuating torque ripple causing noise and vibration, an optimization design technique has been introduced and investigated to find geometric and electric variables by means of combining finite element analysis considering driving circuits and response surface modeling. In this research an effective optimization method based on a response surface modeling has been used to overcome the modeling noise in formulating an objective and constraint and the cumulative numerical inaccuracy.
