This paper presents a new robust DTC-SVM control system for high performance induction motor drives fed by a matrix converter with

variable structure - model reference adaptive control scheme (VS-MRAC). It is possible to combine the advantages of matrix converters

with the advantages of the DTC strategy using space vector modulations and a deadbeat algorithm in the stator flux reference frame.

The lumped disturbances such as parameter variation and load disturbance of the system are estimated by a neuro-sliding mode

approach based on model reference adaptive control (MRAC). An adaptive observer is also employed to bring better responses at the

low speed operation. Simulation results are shown to illustrate the performance of the proposed system.
