Predictive torque and flux control with reactive power minimization for a multi-drive indirect matrix converter system operating at fixed switching frequency

摘要

Multi-drive power converters have been developed to control two or more machines using a single device. However, they require complex multi-objective and reliable control schemes. Based on the above, this paper presents a proposal of multi-drive topology based on an indirect matrix converter using a predictive control scheme operating at fixed switching frequency to control two independent three-phase induction machines. The performance of the system is evaluated by means of simulation results in terms of speed, torque and flux tracking to validate the control algorithm.
