A predictive control strategy applied to a matrix converter based induction machine drive is presented in this paper. The strategy features the advantages of the direct torque control (DTC) and the predictive control, verifying its robustness throughout its behavior analysis under an unbalanced AC supply. The predictive control approach is based on the model of the converter-machine system. Such model...
This paper presents and compares two strategies to generate sinusoidal output voltage waveforms and unitary displacement power factor on the input side using predictive control with an indirect matrix converter. These objectives are accomplished using two different predictive control schemes on the input side: minimization of instantaneous reactive power and imposed input sinusoidal currents. Predictive...
In this paper is presented an alternative to generate sinusoidal output voltage waveforms using predictive control in an indirect matrix converter while achieving sinusoidal source currents on the input side. These objectives are accomplished by using a predictive control scheme which calculates the future values of the variables to be controlled in order to choose the converter state that produces...
This paper presents a control scheme applied to the Direct Matrix Converter (DMC), which combines the advantages of the predictive control and active damping to reduce the resonance of the input filter. A discrete-time model of the converter and the load is used to predict the behavior of the input reactive power in the supply side and the output currents for each valid commutation state. The approach...
