| Abstract: | Summary: This article confers an improved control strategy of a sinusoidal pulse width modulation (PWM)‐operated permanent magnet synchronous machine (PMSM). In a self‐controlled PMSM, space angle between the field magnetomotive force (MMF) and the armature MMF can be considered in various switching instants of the inverter to ensure position estimation. The corresponding rotor position estimation is measured online through a position encoder, and the necessary signal is forwarded to the inverter for producing switching signals. Furthermore, a newly introduced performance indicator, that is, sensor lead angle, is proposed due to the angular displacement between the field MMF and armature MMF at different switching combinations. It is emphasized that with few modifications of the position encoder, near‐sinusoidal armature current response generates lesser torque ripples. Various dynamic behaviors of the PMSM is determined and eventually simulated through MATLAB simulation for various sensor lead angle with unanticipated variation in the load. Furthermore, some case studies are also presented to illustrate the flexibility of the control scheme in several operating environments. To verify the efficacy of the proposed concept, necessary test results are also executed. Additionally, one buck converter‐fed voltage source inverter acting as a current source inverter is designed and implemented in the real‐time test‐bench. Finally, the outcome of simulation and the experimental observations warrant the credibility of the proposed strategy employed in electric propulsion. [ABSTRACT FROM AUTHOR] |
