The reluctance torque of an IPM motor can be effectively utilized by applying the maximum torque per ampere (MTPA) control algorithm, which improves the efficiency and the power density of the motor. However, the motor is unable to operate accurately on the MTPA curve due to the parameter mismatch caused by magnetic saturation and/or temperature variation. This paper proposes the d-axis inductance,...
Flexible supply contracts with options have been proposed to supply chains with long lead-times, short selling seasons and high demand uncertainties to improve the performance. In this paper, we analyze the risks of introducing options, and find that even if providing a higher expected profit at the beginning of a planning horizon, supply contracts with options may have risks associated with a worse...
