Model Predictive Control of Two Separate Induction Machines using Dual-Output Indirect Matrix Converter

Predictive torque and flux control methods for two separate induction machines fed by dual-output indirect matrix converter is presented in this paper. Mathematical models of induction machine and power stage are used to predict future behavior of control objectives and best switching combination is selected by evaluating multi-objective cost function. Basically, torque and flux errors are considered in a user defined cost function and proposed control approach aims to minimize these errors. The method is validated through simulation results where it is shown that dual-output indirect matrix converter combined with predictive control approach can control two induction machines independently.
