对比分析了变频电源控制策略的几种方法。针对变频电源的小信号模型,提出采用超前-滞后补偿对系统进行校正,分析了该控制策略的特性并针对变频电源进行设计。实验结果验证了方案的可行性。
Several methods of frequency control strategy are compared and analyzed. Aiming at the small signal model of variable frequency power supply, the system is calibrated with lead-lag compensation. The characteristics of this control strategy are analyzed and the design of variable frequency power supply is carried out. The experimental results verify the feasibility of the scheme.
