Predictive torque control (PTC) is based on the prediction of motor torque and stator flux for all possible voltage vectors of power converter. These predictions are derived from a mathematical model of the motor that depends on the motor parameters. But, these parameters may not match with their actual values. These parametric uncertainties lead to inaccurate predictions of torque and stator flux...
Multiphase machines are superior to three-phase machines with high reliability and large power capability. In the post-fault operation when one phase of an induction machine is open circuit, model predictive control has been proved to have rapid current, torque and speed response. However, the mathematical model in post-fault operations of multiphase permanent magnet (PM) machines is quite different...
The usual major approaches for current control in hard switched inverters are ramp comparison, hysteresis control. The former involve PI controller and suffer from poor transient performance, and the latter requires complex analog circuitry to give a constant switching frequency. This paper presents a simplified predictive current control algorithms and its application to a voltage source inverter...
