Abstract:Model predictive control (MPC) techniques are gaining importance in the field of power electronics and drives. In the recent years, MPC techniques are usedas an alternative to the use of traditional proportional-integral based controllers. MPC offers multivariable control and facilitates the implementation of system constraints directly into the controller. This technique is adopted for an open-end winding induction motor (OEWIM) which utilizes two two-level inverters for the synthesis of three-level output voltage.The generation of three level voltage using two, two level inverters, generation of Common Mode Voltage (CMV) and the need for its elimination in the dual inverter fed open end winding induction motor drive will be discussed.

The seminar talk mainly covers a multivariable predictive current control (PCC) method that is proposed for the OEWIM drive. The inclusion of system variables/constraints into the objective function with PCCby considering control variables like switching commutations, CMV etc. and their effect on the performance of the dual-inverter fed OEWIM drive will be discussed. Besides, a field oriented control (FOC), envisaged in stator reference frame will be presented with complete CMV elimination. Detailed simulation results and experimentally obtained results will be presented that clearly demonstrates accomplishment of the set objectives. Performance of both FOC and PCC methods under various test conditions on a laboratory test rig will be discussed.
