Fuzzy Logic Controlled 6-Phase PMSM Drive Under Various Operating Conditions

Six-phase permanent-magnet synchronous motor (PMSM) drives are utilized for various applications in various fields including electric vehicles, industries, agriculture, food technology etc. novel control methodologies must be implemented on six-phase PMSM drives to achieve better responses under various operating conditions. Hence Fuzzy Logic Controllers (FLCs) based speed control strategy is developed in this paper for regulating speed under various situations. The FLC attains a significant degree of dynamic performance by employing the vector control technique. Proposed FLC based Field-Oriented Control (FOC) is incorporated within the speed and current regulation mechanisms of the six-phase PMSM drives. The performance of the FLC based FOC with PMSM drives is evaluated through the design and simulation conducted in MATLAB, taking into accounts various operating conditions. The FOC exhibits enhanced resilience and efficiency in tackling the nonlinearity issues occurred in six-phase PMSM drive. The simulation results have validated the effectiveness of the proposed controllers.
