Abstract: Abstract Prediction of aero-engine performance in the sub-idle regime is becoming increasingly important. Performance prediction tools rely on component maps to enable system-level simulations. Methods to obtain compressor sub-idle maps have traditionally relied on low-order… read more here.

DOI: 10.1109/access.2020.3003654
Abstract: Active-short-circuit and locked-rotor modes are common abnormal operations in new energy vehicles. The IGBT junction temperature measurement for these two operating conditions is a challenging problem due to the unexpected large current and the asymmetric… read more here.

DOI: 10.1109/tia.2020.2998994
Abstract: This article proposes a current-scaling gain-compen-sation algorithm for motor drive applications under the locked-rotor condition. In heavy industrial applications, such as elevators and cranes, initial commissioning tests are performed with the rotor locked. To compensate… read more here.
