This paper proposes a mathematic nonlinear model of phase flux linkage in terms of Fourier series expression and a phase torque model based on adaptive neural fuzzy inference system (ANFIS) to a 6/4 switched reluctance motor(SRM). The novel model for SRM and the switched reluctance drive system based on Matlab/simulink is developed. The various control strategies, such as the chopped current control...
This paper presents the dynamic modeling, prediction, control and experimental aspects of a switched reluctance starter/generator (SRS/G) system. The proposed model utilizes the Fourier series in expression of current dependent arctangent function to characterize the relationship among phase current, rotor position, flux linkage and torque characteristics. Second, a simulation model along with their...
This paper deals with investigation on iron loss analysis of line-start permanent synchronous motor (PMSM), which is applied in some industrial field and its load condition and voltage changes frequently. Time-stepping finite element method (T-S FEM) is employed to calculate the loss density in iron-core of PMSM with considering the harmonics of the flux density, and the total iron loss can be obtained...
Accurate information of rotor permanent magnet field is needed in permanent magnet synchronous motor(PMSM) control, but this information is variable under demagnetization conditions, such as high temperature or peak current. Nonsinusoidal flux density distribution caused by demagnetization induces to torque ripple, which degrades the PMSM drive performance. To estimate flux magnitude, a Kalman filter...
