提出将重复控制应用到三相四桥臂逆变器的两种控制方案.一种是在同步旋转坐标系下对d,q,O坐标轴分别进行电压、电流双闭环控制的基础上,对零轴增加蓖复控制器;另一种是直接在a,b,c坐标系F对各相电压外环进行重复加PI控制,对电流内环进行比例控制,此方案思路简单明了且具有较好的带非线性负载的能力,控制效果得,到了明显的改进.两种控制方案在一台基础TMS320F2812型DSP的IGBT三相四桥臂逆变器上进行了实验验证.

Two different schemes for the controlling the three-phase four-leg inverter based on repetitive control is pro-posed.One is the closed loop controll of voltage and current control in the d,q and 0 aixs respectively,and a repetitive control is added into 0 aixs.Another control is based on the a,b ,c aixs combining the PI controller with repetitive control and PI control,which can achieve the same effect as the first one.Further more the scheme has perfect abilities of adapting non-linear loads,and the control effect is improved.Both of the schemes have been validated by a three-phase four-leg in-verter based on TMS320F2812 DSP.
