Project: Electric Drives Based on Matrix Converters

Acronym: MATRIX
Main Objective:
The main objective of this project is to develop an electric drive, based on matrix converters, with self-diagnostic and fault-tolerant capabilities. The drive, which will rely on the use of induction motors and PMSMs, will allow to detect and locate any fault in the matrix converter. After its detection, the control system of the drive will enter in a fault-tolerant operating mode, according to which the control strategy will be modified in order to minimize the consequences of the fault and thus maintaining the system running, although with degraded performance.
Besides the detection of faults in the matrix converter, and in the case of the induction motor drive, the integrated diagnostic system should also be able to detect faults in the motor, namely stator and rotor faults, bearing faults and airgap eccentricity.
The drive obtained with these new features combines the advantages of the matrix converter with the high reliability granted by the integrated and fault-tolerant diagnostic/control system.
