The reluctance torque of an IPM motor can be effectively utilized by applying the maximum torque per ampere (MTPA) control algorithm, which improves the efficiency and the power density of the motor. However, the motor is unable to operate accurately on the MTPA curve due to the parameter mismatch caused by magnetic saturation and/or temperature variation. This paper proposes the d-axis inductance,...
High performance interior permanent magnet synchronous machines show nonlinear magnetics due to saturation and cross-coupling. Nonlinear differential equations describe these phenomena and make feedback control challenging. This paper presents a predictive control method to precisely control the dynamics of these machines. Four real-time capable strategies to online identify transient trajectories...
A predictive control scheme to control the phase currents of a three-phase power converter coupled to the electric grid by means of an LCL network is developed. This kind of coupling offers several advantages when compared to pure inductive coupling networks, namely a greater attenuation of switching harmonics and a smaller size. Equations that model the behavior of the current through the LCL network...
