Aiming at Brushless DC Motor (BLDCM) with a Hall rotor position sensor, this paper presented the design method and implementation of BLDCM control system based on the low cost sine-wave driving method. The period and amplitude of the modulating sine wave were obtained according to the position and velocity information included in the three-phase Hall signals. Then on this basis, the three closed-loop...
This paper presents a new method of vulnerability control for power system by smart demand response (SDR) to insure system vulnerability value kept at a steady level. Vulnerability model is based on sensitive technology (ST) and complex network (CN) theory to reflect physical and structural characteristics of power system. In this paper, ST is adopted by line outage distribution factor (LODF) to show...
