Constraint Satisfaction in Current Control of a Five-Phase Drive with Locally Tuned Predictive Controllers

The problem of control of stator currents in multi-phase induction machines has recently been tackled by direct digital model predictive control. Although these predictive controllers can directly incorporate constraints, most reported applications for stator current control of drives do no use this...
