Sensitivity analysis of the control of a three-phase open-end winding H-bridge drive

This work proposes a sensitivity analysis of the control of a 3-phase open-end windings PMSM H-bridge drive. The study issues are focused on the robustness of Space Vector PWM modulation strategies towards unavoidable operating faults. The considered faults are due to the imperfection of the PWM hardware implementation, the power converter nonlinearity and the harmonic distortion of the PMSM phase electromotive forces. This theoretical study is validated by experiments on a 3 H-Bridge drive test bench based on an induction motor.
