摘    要:针对400Hz恒压恒频(CVCF)逆变器,提出了一种模糊.重复混合控制方案。模糊PD控制器用于改善系统处于振荡或过冲时的动态性能,重复控制器用于稳态时输出高质量的正弦电压。因此模糊PD控制器和重复控制器的混合可以利用它们各自的优点,该控制方案采用TI的DSP芯片TMS320F240在一台400Hz、5.5kW样机上得以实现。实验结果验证了所提出的控制方案不仅能在稳态时获得低THD的输出电压,而且在负载突变时获得了较好的动态性能。

Abstract:In this paper a hybrid fuzzy-repetitive control scheme for 400Hz constant-voltage constant-frequency (CVCF) inverters is presented. The fuzzy PD controller is used to improve transient performance whenever the system exhibits an oscillatory or overshoot behavior. Repetitive controller is applied to generate high-quality sinusoidal output voltage in steady state. Thus, the fuzzy PD controller and repetitive controller can be combined to take advantage of their positive attributes. The control scheme is implemented using a TI TMS320F240 DSP in a 400Hz 5.5kW prototype. Experimental results prove that the proposed control scheme can achieve not only low THD during steady-state operation but also fast transient response subject to load step change.
