The classic model predictive control presents a variable switching frequency which could produce resonances in the input filter of the matrix converter, affecting the performance of the system. In this paper a model predictive control strategy is proposed with fixed switching frequency operation which is enhanced with an active damping method in order to mitigate resonances of the input filter. The...
The direct matrix converter has twenty-seven available switching states which implies that the implementation of predictive control techniques in this converter requires high computational cost while an adequate selection of weighting factors in order to control both input and output sides of the converter. In this paper, two indirect model predictive current control strategies are proposed in order...
The classic model predictive control presents a variable switching frequency which could produce high ripple in the controlled waveforms or resonances in the input filter of the matrix converter, affecting the performance of the system. This paper presents two model predictive control strategies with fixed switching frequency operation which allow a better performance of the system. The operation...
In this paper an indirect model predictive current control strategy is proposed. The proposed method simplifies the computational cost while avoiding the use of weighting factors. Weighting factors are an issue for model predictive control in a direct matrix converter due to the large number of available switching states and necessity to control both input and output sides of the converter.
The following paper presents a novel indirect model predictive control strategy for a direct matrix converter (DMC). The direct matrix converter has a large number of available switching states and therefore the implementation of predictive control techniques require high computational resources. In addition, the simultaneous selection of weighting factors for the control of input and output variables...
This paper proposes a predictive control technique for an indirect matrix converter. The proposed control strategy gives sinusoidal waveforms at both the input and output of the converter without any weighting factor in the cost function and, at the same time, giving operation at a fixed switching frequency. Simulation results with an unbalanced ac-supply validate the proposed method under both steady...
In this paper a predictive control technique for an indirect matrix converter is proposed. The control strategy allows to impose a sinusoidal waveform in both the input and output current of the converter without any weighting factor in the controller and, at the same time, the operation at fixed switching frequency. Simulation results validate the proposal under both steady and transient states which...
