摘要
异步电动在各行各业越来越广泛,对转矩的控制提出了更高的要求。本文针对转矩控制的问题,将三桥臂逆变器驱动单相异步电机作为研究对象,利用空间矢量脉宽调制技术(SVPWM)对目标电压进行调制输出,利用MATLAB软件对转矩控制系统进行了建模和仿真分析,试验数据表明了最大转矩得到了提高,最大转矩方法也能很好的消除由于电机不对称而产生的转矩以及转速的波动,并且具有较好的抗扰动能力。
Asynchronous motor is more and more widely used in all walks of life,which puts forward higher requirements for torque control.Aiming at the problem of torque control,this paper uses three leg inverter to drive single-phase asynchronous motor as the research object,and uses space vector pulse width modulation(SVPWM)to modulate the target voltage.The torque control system is modeled and simulated by MATLAB software.The test data show that the maximum torque is improved,The maximum torque method can also eliminate the torque and speed fluctuation caused by motor asymmetry,and has good anti disturbance ability.
