摘要
针对传统双三相感应电动机直接转矩控制系统的定子谐波电流较大这一问题,在基本SVPWM算法、基本DTC技术的基础上,设计出一种基于十二中间电压矢量的双三相感应电动机DTC系统。在Simulink环境下建立了该系统的各部分仿真模块和总体仿真模型,结果表明,设计的系统能够有效减小定子谐波电流和转矩脉动,从而验证了所提出控制策略的正确性、有效性。
For the problem of large stator harmonic current in direct torque control system of traditional dual 3-phase induction motor,a new dual 3-phase induction motor DTC system based on 12 medium voltage space vectors is designed on foundation of SVPWM algorithm and basic DTC technology.Every partial and general simulation models are established in Simulink.The simulation results show that the designed system can reduce the stator harmonic current and torque ripple effectively,therefore it is verified that the new control strategy is correct and effective.
