摘要
提出了一种基于重复控制和带积分状态反馈控制的逆变电源控制策略,建立了单相电压型逆变电源的状态空间数学模型。重复控制抑制了稳态电压畸变,状态反馈控制改善了动态性能,而引入积分控制,则改善了状态反馈控制的稳态精度。这种控制策略使逆变电源获得了良好的稳态和动态特性。
An inverter control system based on repetitive control and instantaneous feedback control is presented. The state-space mathematical model of the single-phase voltage-source-inverter power supply is derived. Repetitive control is used to reduce voltage distortion, the state feedback control is for the improvement of the dynamic characteristics and the introduction of integral function in the state feedback control reduces the steady-state error. With this scheme, the inverter shows good steady-state and dynamic characteristics.
