摘要：

在六脉波双变量交交变频器中,中频段有级变频调速存在抗干扰能力弱及调速范围窄的问题。在六脉波双变量变频的基础上,文中提出了在中频段采用变频与闭环调压相结合的控制策略。在变频后,该方法通过闭环控制来改变输出电压,进而控制转速。搭建MATLAB仿真模型,以编写S函数的方式控制触发脉冲,分别在电机转速、转矩突变的情况下验证变频与闭环调压相结合的控制效果。MATLAB仿真结果显示,运用该控制策略不仅可以减小系统内存存储空间,提高运行速度,还增加了中频段的调速范围及电机的鲁棒性。

Abstract:

In the six pulse dual variable cycloconverter, there are some problems such as weak anti-interference ability and narrow speed range in the intermediate frequency band.Based on six pulse dual variable frequency conversion, the control strategy of frequency conversion combined with closed-loop voltage regulation in medium frequency band is proposed. After the frequency conversion, this method changes the output voltage through closed-loop control to control the speed. Subsequently, a MATLAB simulation model is built, and the trigger pulse is controlled by S-function, the control effect of the combination of frequency conversion and closed-loop voltage regulation are verified in the case of motor speed and torque mutation. The MATLAB simulation results show that the control strategy cannot only reduce the memory space of the system and improve the running speed, but also increase the speed range of the medium frequency band and the robustness of the motor.

Key words: bivariate, stepwise frequency conversion, switching mode, intermediate frequency section, robustness, closed-loop voltage regulation, speed range, S function
