Simplified Model Predictive Flux Control for Dual Inverter Fed Open End Winding Induction Motor

Recent Achievements in Model Predictive Control Techniques for Industrial Motor: A Comprehensive State-of-the-Art

“…By full mathematical analysis, only the stator flux can be employed in the cost function, as called model predictive direct flux control (MPDFC). Till now, such method has been widely studied by many experts [36], [84], [92], [93]. The cost function for this method is given by g = ψ * αs − ψ αs (k + 1) + ψ * βs − ψ βs (k + 1) (18)…”

“…17. Furthermore, a novel MPTC with a fast response is proposed in [36] for PMSM drives, where the reference torque is converted to reference stator flux-linkage in d-axis and q-axis, totally different from those in α-axis and β-axis as presented in [84], [92]. Besides, Pontryagin's Maximum Principle is applied during the transient process to get much faster dynamic response.…”

“…It can be used for designing the minimum time flux linkage trajectories from the initial state to the reference state. Another control method without weighting factor is presented in [93], where the angle of the flux is obtained by another way, also different from the method as presented in [84], [92]. The block diagram of this control method is illustrated in Fig.…”
