基于7电平T型变换器的SRM改进转矩分配函数控制策略
An improved torque sharing function control strategy for SRM based on a 7-level T-type converter
摘要
Abstract
To overcome the limitations of conventional asymmetric half-bridge converters in terms of driving capability and torque ripple suppression for switched reluctance motors(SRM),an improved torque sharing function(TSF)control strategy with voltage-level vector shift is proposed based on a 7-level T-type converter.First,a novel 7-level T-type converter is constructed with a series-parallel switching function and a T-type structure that generate four additional voltage levels.Subsequently,the TSF's torque hysteresis comparison process is improved,and a voltage-level vector shift strategy is proposed.Torque ripple in the phase change region is suppressed by implementing the voltage-level vector shift through the closed-loop torque control.Finally,simulations and experiments verify that the proposed converter and control strategy not only improve the torque output capability of the motor but also significantly reduce torque ripple.关键词
