There are various unstable situations in IoT environments due to the characteristics of wireless local connections, the faults in IoT devices, and the IoT devices crowd at a unit space. To construct a more stable IoT environment for IoT services, the IoT Routers for the IoT service overlay networks should be constructed solidly first. Our research seeks implementing a reliable IoT environment with...
This paper focuses on the low speed performance of extended electromotive force (EMF) based position-sensorless speed control of surface permanent magnet synchronous motors (SPMSMs) in real-time. It is the first time Morimoto's extended EMF approach is applied to SPMSM and its low speed performance is evaluated by real-time experiments. The results obtained from the designed position-sensorless drive...
We present results of the first field trial ever to include a component of MDM. The demonstrated scenarios all confirm the possibility for a partial upgrade of legacy systems to few-mode technology.
