Matrix converter induction motor drive with DTC-based fuzzy control

This work presents a new fuzzy control scheme based on DTC for a matrix converter induction motor drive. The control scheme decouples the stator flux and the motor torque determining a stator voltage vector with a fuzzy inference system. Simulation results obtained using a model of a 5 kW prototype matrix converter show improvements in the system dynamic response and reduction in the steady-state motor torque ripple.
