Improving performance, energy efficiency and reduced carbon emissions in industrial installations require the enhancement of power quality and reduced EMC/EMI emissions. In this frame, active power filters for improving power factor and harmonics mitigation are gaining interest as FACT devices for smart power networks. This work presents the simulation and analysis of a predictive control method applied...
Industrial installations require high reliability and performance, especially when the power system has a low short-circuit level and non-linear loads injecting harmonics which can generate electromagnetic interferences EMC/EMI threatening functionality and safety related with control and protection systems. Conventional passive harmonic filters compensate reactive power, and reduce parallel resonances...
This paper presents the use of a predictive technique to control the currents in a PMSM, driven by a voltage source inverter. This method allows for a high quality current control without using linear controllers and modulators, resulting in a conceptually simple solution. Simulation an experimental results confirm the good performance of the drive controlled by this method.
This paper presents a predictive strategy for the control of a permanent magnet synchronous motor (PMSM). Our approach allows one to simultaneously manipulate speed and electrical variables, without using any auxiliary linear controller. The high sampling rate, characteristic of this technique, and the limited precision of the typical angle measurement devices, present serious difficulties for this...
The matrix converter features natural bidirectional power flow, sinusoidal current/voltage waveforms, and a reduced size and weighty compared to standard direct static power converters. However, it is sensitive to polluted AC supplies because no storing elements are present and thus any disturbance would reach the load terminals. Typical disturbances in the AC distribution systems are voltage unbalances,...
This paper presents a modified predictive current control strategy which allows one to have control over the spectrum of the load current. The proposed method uses a model of the system to predict the behavior of the current for each possible voltage vector generated by the inverter. For that purpose, at each sampling interval, signal predictions are evaluated using a cost function that quantifies...
