Predictive control of a direct AC/AC matrix converter for power supply applications

Abstract

The use of Model Predictive Control (MPC) is investigated for a three phase to three phase direct matrix converter with input and output LC filter for power supply applications. It allows generation of sinusoidal output voltages and input currents with low harmonic distortion. The work describes in details the design of the proposed finite states model predictive control in conjunction with a full load observer. The proposed matrix converter power supply produces unity input power factor and a perfect tracking of the sinusoidal output voltage, accurately following the imposed reference in the presence of a linear load. A simulation study is presented to validate the proposed control scheme.

“…2, the most relevant techniques correspond to PCC [15]- [24] and predictive torque control (PTC) [25]- [29]. It is also possible to find some implementations of predictive reactive/active power control (PPC) [30]- [33], and predictive voltage control (PVC) [34]- [36] where an filter is used at the output of MC to provide a voltage source rather than a conventional load control function.…”

“…As indicated in Fig. 2 other goals uses for predictive control are also possible in MC applications, including power control [30]- [33] and voltage control [34]- [36]. All these control schemes have been proven in practical implementations and can be analyzed in a similar way to the PCC and PTC in examples discussed earlier.…”

Speed Finite Control Set Model Predictive Control of a PMSM Fed by Matrix Converter

“…This strategy allows to directly control more than one state variable at the same time, using a single control rule. Several authors have applied FCS-MPC to the MC [11,12]. In [13] a method for increasing the efficiency of the converter has been proposed, while in [14] the use of a virtual damping resistor to mitigate the resonances of the input filter is proposed.…”
