A position sensor is required in a Permanent magnet synchronous machines(PMSM) system, which will raise cost and reduced reliability. Sensorless control of PMSM drive overcome these difficul-ties. In the start-up control of sensorless PMSM, may cause a starting failure due to unknown rotor initial position[1].a voltage pulse injection method based on magnetic saturation effect has been proposed[2]...
Resistive switching random access memory (RRAM) is a leading candidate for next-generation nonvolatile and storage-class memories and monolithic integration of logic with memory interleaved in multiple layers. To meet the increasing need for device-circuit-system co-design and optimization for applications from digital memory systems to brain-inspired computing systems, a SPICE model of RRAM that...
As it is not enough to assess the integral reliability of the complex 3D high arch dam-foundation system just from local damage in the deterministic analysis, the improved response surface method is firstly introduced to get the failure possibility of individual uncertain factor, and then PNET method to fix the integral reliability considering several uncertain factors. Then the main works are presented...
