摘要
针对为克服传统矩阵变换器电压传输比低的缺陷而提出的新型Buck-Boost矩阵变换器(BBMC),提出采用鲁棒PID控制策略进行控制。介绍了该控制策略的基本原理,阐述了将其应用于BBMC逆变级控制的具体设计方法,并通过仿真对其控制效果进行了验证。结果表明:该控制策略使BBMC获得了良好的动态和稳态性能,能实现输出电压和频率的任意调节,且直接输出较标准的正弦波而无需滤波环节,谐波含量小,具有一定的应用价值。
Aiming at the new buck-boost matrix converter（BBMC） which was proposed to solve the puzzle of traditional matrix converter with low voltage transfer ratio,a robust PID control strategy was proposed.Firstly the basic principle of this control strategy was introduced.Then the specific design method of this control strategy applied to control the inverter of BBMC was clarified.Finally the validity of this control strategy was tested by simulation.whose results show that the BBMC based on the robust PID control strategy has fine performance of dynamic and steady state,the output voltage and frequency can be modulated optionally,and a normal sine wave with low harmonic distortion can be directly obtained without filtering,which is of certain practical importance.
