An Optimized Twelve Sector Space Vector Pulse Width Modulation control of PMSM Drive

Optimal signal generation and accurate on-time determination of switches are essential for the improvement of an inverter feed drive’s steady-state and transient responses. This work combines a simple classical optimal current generation process with sector segmentation of six SVPWMs to improve drive performance. An average of two adjacent states is used to get six virtual states to segment six sectors into twelve sectors. Simulation is carried out in Matlab-2021 to see the performance of the proposed system. A simulation has shown that the control method is efficient in controlling the speed dynamics and steady-state error. In addition, the ratio of harmonic power loss to total active power loss of the proposed system is less.
