基于新型TSF的车用SRM直接瞬时转矩控制
|
摘要
根据车用工况的需求,以开关磁阻电机的非线性模型为依据,提出了一种基于新型转矩分配函数的改进型直接瞬时转矩控制(IDITC)方案。针对传统转矩分配函数受导通角限制的情况,IDITC将控制中的开通、关断角与转矩分配函数的控制角度进行区分,在满足了各相转矩分配函数之和为1的前提下,扩大了其导通角的范围,并最终通过PI调节对分配转矩不可控区间实施控制。仿真和实验结果表明,IDITC能有效抑制系统的转矩脉动,提高系统的效率。
According to the non-linear model of switched reluctance motor( SRM) and the vehicle condition,an improved direct instantaneous torque control( Improved Direct Instantaneous Torque Control,IDITC) based on the modified torque sharing function was proposed. Due to the traditional torque sharing function was limited by the conduction angle,IDITC distinguishes the turn-on and turn-off angles of SRM from the control angles of the torque sharing function. The range of conduction angle of torque sharing function was expanded when the sum of the functions was 1. The uncontrollable section of the torque was controlled by the PI control. Simulation and experimental results show that IDITC can effectively reduce the torque ripple and improve the efficiency of the system.
