摘　　要：针对间接矩阵变换器(Indirect matrix converter,IMC)-异步电机(Induction machine,IM)调速系统换流复杂的问题,提出一种零电流换流-模型预测控制(Zero current control-model predictive control,ZCC-MPC)方法。在逆变级,控制周期内采用开关状态组合代替单一的预测开关状态,以保证整流级总是在逆变级为零电压矢量时发生换流。仿真结果表明系统具有良好的动静态性能,并且整流侧开关动作时,中间直流电流总为0,整流级换流得以简化。In order to solve the problem of complex commutation in indirect matrix converter (IMC)-induction machine,(IM) speed control system, a zero current control-model predictive control (ZZCC-MPC) method is proposed. In the inverting stage, the combination of switching states is used instead of a single predictive switching state in the control cycle to ensure that the rectifier stage is always commutated when the inverter stage is a zero voltage vector. The simulation results show that the system has good dynamic and static performance, and when the rectifier side switch operates, the intermediate DC current is always 0, and the rectifier stage commutation is simplified.
