Fixed switching frequency predictive control for a multi-drive indirect matrix converter system

Multi-drive power converters have been developed to reduce the implementation cost in systems that requires two or more machines working together but they require complex multi-objective and reliable control schemes. This paper presents an indirect matrix converter as the power stage to control two independent three-phase induction machines in a multi-drive scheme using a predictive torque and flux control strategy operating at fixed switching frequency. The performance of the system is evaluated by means of simulation results in terms of torque and flux tracking to validate the control algorithm.
