摘要
提出一种基于重复控制和多环反馈控制的复合控制方法,该方法可以提高用于400Hz中频电源中的单相恒压恒频PWM逆变器的动态和稳态响应。其中,重复控制器用于在稳态情况下产生高质量的输出电压。多环反馈控制器则用来改善系统的动态特性。该控制策略已在一台基于DSP全数字控制400Hz中频电源装置上得到了验证。
This paper presents a hybrid control scheme based on repetitive control and multiple feedback loop control to improve both the transient and steady-state responses of a single-phase CVCF PWM inverter used in 400Hz medium frequency power supply.The repetitive controller is used to generate high-quality sinusoidal output voltage in the steady-state.The multiple feedback loop controller is applied to improve dynamic performance of the system.The proposed control strategy has been proved effective on a DSP based fully digital-controlled 400Hz medium frequency power supply equipment.
