Modified PWM Direct Instantaneous Torque Control System for SRM

Torque ripple is a defect of switched reluctant motors. DITC (direct instantaneous torque control) harnessed to solve the problem as traditional method, which superior TSF (torque sharing function). In this paper, new controller proposed with modified hysteresis and PWM in DITC. With algorithm, error will be reduced The algorithm effective improve sample 0 status period. based on application zero asymmetric half bridge, implemented buffer zone. case big error, mitigate under characteristic fast responding. small errors, equivalent strategy, has adopted essence impulse method. designed reduce responding time minimize been harness different functions errors. Based final simulation experimental results, speed reduction output are enhanced effectively.
