Multi-phase motors are usually designed to have the concentrated winding and non-sinusoidal air gap flux density distribution in order to maximize the electromagnetic torque. To realize the object, phase voltage of the multi-phase motor should have some special harmonics corresponding with the air gap flux density. In this paper, a novel SVPWM named Harmonic Space Vector Injecting SVPWM (HSVI-SVPWM)...
Research in Information Retrieval (IR) experienced a paradigm shift from first having too few documents to search from to now having way too many of them. When users have trouble finding relevant documents, they tend to become frustrated and give up searching. Scholars have attempted to reduce instances of search frustration via query expansion, information filtering, and incorporating user feedback...
The error equation of the azimuth misalignment angle for SINS on the static base is nonlinear, and it's an urgent problem to align it when the angle is large. This paper proposes a method for the initial alignment of large azimuth misalignment based on Krein space linear estimation. The sum quadratic constraint (SQC) for nonlinear system is obtained by using Lipschitz condition of nonlinearity. Thus...
To increase power and improve performance of the inverter, a topology of three-phase H-bridge inverter is proposed in this paper, the voltage vectors of the three-phase H-bridge inverter are defined and computed, and the distribution of those voltage vectors is analyzed. In terms of the vector distribution, the influence of every voltage vector on flux-linkage and torque is analyzed, and an optimal...
