| 摘 要： | 分析了组合式三相逆变电源在三相abc坐标系和同步旋转dq坐标系下的数学模型,根据三相输出电压在dq坐标系下的特点,提出将瞬时PI控制和重复控制相结合的复合控制方案,利用重复控制器抑制稳态谐波畸变,利用PI控制器提高系统的动态响应速度,抑制基波扰动。该复合控制方案通过一台450kVA三相大功率逆变电源试验验证,相关试验结果表明该方案可以得到优良的稳态和动态控制性能。

| Abstract: | Mathematical models of a combined three-phase inverter in three-phse abc coordinate system and rotate dq coordinate system are analyzed.Based on the features of three-phase output voltage in dq system,a synthesized control scheme combined immediate PI control with repetitive control is proposed.The repetitive control is used to restrain steady-state voltage wave distortion and PI control can improve dynamic performance of the control system.The control scheme is verified by a 450kVA three-phase high-power inverter and results prove that the proposed scheme can achieve good static performance as well as dynamic performance. |
