One of the main drawbacks of the implementation of predictive control in a direct matrix converter is the high computational cost and the adequate selection of weighting factors in order to control both input and output sides. In this paper is proposed an indirect model predictive current control strategy enhanced with a fixed switching predictive strategy and an active damping implementation. With...
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...
A modulated model predictive control (M2PC) scheme for an indirect matrix converter is proposed in this paper, including an active damping method to mitigate the input filter resonance. The control strategy allows the instantaneous power control and the output current control at the same time, operating at a fixed frequency. An optimal switching pattern is used to emulate the desired waveform quality...
Passivity based control (PBC) method is an energy based control method. The total energy of the system is expressed as a sum of stored energy and dissipated energy. This technique deals with energy shaping as well as damping injection and tracking which is achieved via Hamiltonian operator. Passivity based control is developed by satisfying dissipation matching condition. In this paper the types of...
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.
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...
A predictive control scheme for the indirect matrix converter including a method to mitigate the resonance effect of the input filter is presented. A discrete-time model of the converter, the input filter and the load is used to predict the behavior of the reactive power and the output currents for each valid switching state. The control scheme selects the state that minimize the value of a cost function...
