Synchronous cars are no doubt the simplest gadget to force commercial creation structures and robots with precision and rapidity. Their keep watch over legislations is hence severe for combining whilst excessive productiveness to lowered power consummation. so far as attainable, the regulate algorithms needs to take advantage of the houses of those actuators. for that reason, this paintings attracts on good tailored types caused by the Park’s transformation, for either the main conventional machines with sinusoidal box distribution and for machines with non-sinusoidal box distribution that are an increasing number of utilized in undefined. either, traditional keep watch over innovations like vector keep watch over (either within the synchronous reference body or within the rotor body) and complex keep watch over theories like direct regulate and predictive keep an eye on are completely provided. during this context, an important position is reserved to sensorless keep watch over that's a major and important factor in tomorrow’s motors.Content:

Seen from the outside, the magnet is equivalent to an air coil crossed through by a constant current; – we will see that the saliency introduces into the models a specific parameter (noted Ls 2 ) and that it is sufficient to pose that this parameter is equal to zero, to model a non-salient pole machine. ), far away from the physical representation, but which makes it possible to easily write the mathematical machine model. 4. 2. Hypotheses on the motor The conventional motor modeling is based on the conventional hypotheses of the “well-built machine in the meaning of Park”.
3. 67] or: The zero-sequence components are identical in the α −β and d-q reference frames. 12). 12. 73] constitute the dynamic mathematical model of the axis driven by the synchronous motor. From it, we can give an “input-output diagram”. 13. This complete dynamic model will be our “simulation model” which, completed by the equations of the controllers, will help us to judge the controls performances. It is necessary to distinguish this “dynamic model” (which is as complete as possible) from the simplified “control models”, that we will use in Chapters 2 to 4 to conceive (or “to design”) often simplified controllers.
We choose here an analytical approach, that we consider as a heuristic extension of the Park transformation ([GRE 93], [GRE 95], [GRE 97], [GRE 98], a method reused in [MON 04]). For more details, we can read the chapter in [GRE 04]. We give here a short presentation. 3) has several “good” properties: the reference frames first deduced by the Clarke or Concordia, transformation and then by an angle rotation p1 ⋅ θ are orthogonal. Moreover, we decide to choose a normalized transformation, preserving the power.
