The petroleum product has seen a drastic demand in the recent past. Biofuels are the only solution to overcome this power crisis. In the view of sustainable energy development, biodiesel and its additives have become the best options for fossil fuel-based engines. In this work, a biodiesel mix was used to show the possible utilization of different biofuels. An experimental investigation was car...

An injection-locking scheme, involving a single-frequency master laser monolithically integrated with unidirectional whistle-geometry semiconductor microring laser, has been proposed for enhanced ultra-high-speed performance. Greatly high-speed modulation performance of the strong-injection-locking scheme predicted in numerical calculations. In our previous analysis, however, linear coupling be...

In the paper the principle and performances of the pulsating current injection based sensorless control of permanent magnet synchronous motor (PMSM) are analyzed theoretically and investigated by simulations. In the analyses, the effects of the speed EMF terms and the deviation between the actual d-axis high-frequency current and the command, which results from the limited gain and bandwidth of...
