Sensorless predictive current control (PCC) for an induction machine is proposed in this study. In the controller, the errors between the current references and the predicted values are evaluated; therefore, it guarantees good current behaviours which are essential to the low-voltage drives. By designing proper adaptive scheme and gain matrix, a stable sensorless PCC system is achieved. Furthermore,...
Three-phase four-leg inverter has powerful ability to effectively treat unbalance and nonlinear loads, which outputs three phase symmetrical voltages. A novel control scheme with PD output voltage instantaneous-value feedback inner loop for voltage PID is proposed based on the model of three-phase four-leg inverter. The inner loop is designed to improve dynamic performance and the voltage external...
