Predictive Direct Torque Control of Matrix Converter fed Permanent Magnet Synchronous Machines

A predictive Direct Torque Control method for Matrix Converters fed Permanent Magnet Synchronous Machines drives is proposed in this paper. The voltage vector from the Matrix Converter which ensures minimum torque ripple is selected based on a predictive algorithm. A look-up table for Direct Torque Control using Matrix Converters has been developed which delivers a set of three vectors, at every sample period, that fulfil the torque and flux demands. The predictive algorithm computes the torque error that would be present applying each vector and selects the one that contributes with the minimum error. Simulation results, which confirm the good performance of the proposed predictive Direct Torque Control using Matrix Converters are shown.
