“…This model involves three consistent fundamental equations: (1) a circuit equation expressing the electromagnetic dynamic characteristics of the model, (2) a torque equation expressing the instantaneous relations in torque generation, and (3) an energy transfer equation expressing the dynamics of energy transfer, in general γδ-coordinates. In connection with the latter method, Senju and colleagues [13][14][15] applied to SP-PMSM a modeling method proposed for induction motors by Mizuno and colleagues [17].…”

SUMMARYThis paper investigates and proposes new system structures for vector control of permanent-magnet synchronous motors (PMSMs) with core loss. The proposed vector control systems have the following versatile features. (a) The systems employ the structures allowing control of the stator current through control of the load current. (b) The systems employ unique "stator voltage feedback-use" structures in order to accomplish simply the load current control. (c) The produced torque is directly related to the load current, and the precise torque control can be attained through the load current control. (d) The relation between produced torque and the load current is nonlinear for salient-pole PMSMs similar to the case of no core loss, and a variety of the load current commands can be selected from viewpoints of minimum loss and/or wide speed range drives. The system structures add no constraint to the selection of the load current commands. (e) In addition to the torque control, the speed control can be allowed, where linearity between output of the speed controller and produced torque is kept. The validity of versatile features is verified through the numerical experiments.

“…As to the mathematical models for vector control representing the dynamics of induction motors in differential equations taking into account stator core losses, the proposal by Mizuno and colleagues was probably the first in Japan (hereafter referred to as the Mizuno model) [20]. In the Mizuno model, the starting point in the construction of the model is as follows.…”

This paper proposes new mathematical models with stator core (iron)‐loss factor for induction motors intended to generate precise and/or efficient torque via vector control. The proposed models have a structure in which the stator core‐loss resistance is equivalently placed purely in parallel with the stator inductance. It is shown that stator core losses consisting of eddy‐current and hysteresis losses can be properly represented by the parallel resistance, and, in particular, eddy‐current loss by a constant one. The models are composed of three basic vector equations in the general frame of an arbitrary angular frequency, such as fourth‐order differential equations describing motor dynamics, the torque equation, and the energy conversion equation. These basic equations are essential for vector control design taking core loss into consideration. The proposed models are most compact in the sense of the number of both the employed parameters and the interior states of the motor. Compactness is an important factor for modeling and is useful for designing vector control systems. © 2000 Scripta Technica, Electr Eng Jpn, 134(1): 64–75, 2001
