Maximum torque per ampere (MTPA) control scheme for internal permanent magnet (IPM) machine is presented in this paper. Proposed control scheme was developed based on measurement of only DC link quantities eliminating the necessity of 3-phase current feedback. The scheme employs an online search algorithm with initial condition computed from a-priory system information. Hybridization of search based...
Rainflow algorithms are one of the best counting methods used in fatigue and failure analysis popularly used in semiconductor lifetime estimation models. However, the rainflow algorithm used in power semiconductor reliability does not consider the time dependent mean temperature calculation. The equivalent temperature calculation proposed by Nagode et al is applied to semiconductor lifetime estimation...
This paper presents a saliency-based position sensorless drive of permanent magnet (PM) machines using a single current sensor for cost-effective applications. For the single current sensor system, the dc-link current is measured for the reconstruction of three-phase currents. The phase current reconstruction can only be realized when active voltages are applied. This limitation results in six immeasurable...
Model reference adaptive system (MRAS) is usually employed for the rotor position/speed estimation in sensorless interior permanent magnet motor (IPMSM) drives, and the adjustment of control parameters in MRAS is a key issue for the IPMSM drive system with the cyclic fluctuating load. In order to avoid the complicated manual tuning of the control parameters, a new MRAS scheme based on fuzzy logic...
