The original direct power control (DPC) is known to give a fast response under transient conditions. However, active power, reactive power and current pulsations occur in steady-state operation. A family of variable structure controllers for the doubly fed induction generator (DFIG)-based wind turbine system is presented, using the principles of an active and reactive power controller known as modified...

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...
This paper presents a new robust sensorless control system for high performance induction motor drives fed by a matrix converter with variable structure. The lumped disturbances such as parameter variation and load disturbance of the system are estimated by a variable structure approach based on model reference adaptive scheme. A Reduced Order Extended Luenberger Observer (ROELO) is also employed...
