Performance Analysis of Space Vector Approach Based Field Oriented Control of Indirect Matrix Converter Fed PMSM Drive

This paper presents a comprehensive performance analysis of the improved space vector approach based field-oriented control (FOC) technique to a permanent magnet synchronous motor (PMSM) drive, fed by an indirect matrix converter (IMC). PMSMs have gained significant popularity in different commercialized applications owed to their high efficiency, robustness, and precise control characteristics. The IMC has emerged as a promising power electronic interface for PMSM drives, offering advantages such as bi-directional power flow, no use of storage elements, low harmonic distortion and high power density hence reduced weight and volume. However, its effective integration with PMSM drives remains a challenging task, especially when high-performance control techniques like FOC are employed. The proposed method aims to overcome the inherent limitations of the IMC by achieving robust and efficient control of the PMSM drive emphasising its role in regulating the stator currents and rotor flux for precise speed and torque control. Simulation results are provided to substantiate its high-level accomplishment in terms of reduced ripple in torque, faster dynamic response, and lower harmonic content.
