This paper deals with the sensorless vector controlled five-phase permanent magnet synchronous motor (PMSM) drive based on a sliding mode observer (SMO). The observer is designed considering the back electromotive force (EMF) of five-phase permanent magnet synchronous motor. The SMO structure and design are illustrated. Stability of the proposed observer is demonstrated using Lyapunov stability criteria...
In this paper space vector model of a fifteen-phase voltage source inverter (VSI) is presented. The space vector Pulse Width Modulation (SVPWM) of a fifteen-phase voltage source inverter (VSI) with the aim of producing sinusoidal output waveform, is illustrated. Generalized space vector theory is used to model the inverter and the SVPWM. As per the general inverter switching theory there are 215 =...
Multiphase drives are now becoming serious competitor to traditional three-phase drives due to reasons of better fault tolerant property and reduced per-phase converter rating that are especially suited to high power drives application. One of the major factor of widespread research on multiphase drive are the availability of high computational power of control platforms such as DSP and FPGAs. With...
Multiphase electric drives have been investigated and proposed for applications where the highest overall system reliability and the reduction in the total power per phase are required. This paper deals with the high performance Backstepping control strategy which is based on laws allowing an explicit control of system stability in closed-loop operation of five-phase induction motor drives. This control...
