A closed form solution is presented for the transient and steady-state response of surface permanent magnet synchronous machines to single FET short circuit failure in the drive. PWM techniques such as sine and discontinuous switching schemes are compared with respect to the motor performance under such fault condition. With the help of the analytic model the sensitivity of the key control parameters...
Due to simple and robust configuration, and without any coils and magnets on movers, a tubular linear switched reluctance actuator (TLSRA) is a promising candidate for applications of frequently reciprocating linear motion, such as linear compressors and automotive active suspension sys-tems[1-2]. For air-gap in a TLSRA, there are the longitudinal and transverse magnetic paths due to various mover...
The determination of the number of formation cars is an important part of making a scheduled freight train plan, and it also has a large influence on the benefits of railway freight transportation. First, the influences that affect the number of formation cars are analyzed. Secondly, taking the maximum freight transport benefits as an objective, and comprehensively considering the primary factors...
Charge Coupled Devices (CCDs) have been successfully used in several high energy physics experiments over the past two decades. Their high spatial resolution and thin sensitive layers make them an excellent tool for studying shortlived particles. The Linear Collider Flavour Identification (LCFI) Collaboration has been developing Column-Parallel CCDs for the vertex detector of a future Linear Collider...
