 Control and Applications of Multi-phase Induction Machines







Multiphase induction machines are attracting an increasing attention due to their inherent advantages over three-phase machines, e.g. reduced per phase power rating, improved reliability and increased degrees of freedom. Compared with three-phase Induction machines, variable speed multiphase induction machine provide a higher power range by utilizing low-power switching devices, due to the higher number of inverter phase legs and higher torque density. These properties are in particular important for applications in which power supply voltage is limited, the torque oscillation amplitude is required to be decreased and the fault tolerant ability is required. Indeed, the fault-tolerance capability is one of the most attractive properties of multiphase machines for industrial applications. Especially,  for drive systems with high reliability in non-stop operation conditions, which are known for high economical and safety repercussions caused by fault occurrence, e.g. in electrical vehicles, traction, ship propulsion, and other safety-critical applications such as electrical helicopters.

The workshop will deliver the base knowledge on multiphase induction motor drives. The mathematical model, exemplary motor constructions, drive control methods including speed sensorless control, multi-phase voltage inverter control and furthermore the operation in faulty states will be shown.

************ Workshop 2 ************ 


Type-2 fuzzy logic

New: Participants in the workshops 2 should bring their personal          Laptop  with Matlab installed.





The principal problem encountered with uzzy systems is that they can deliver nonsatisfactory performances in face of uncertainty and imprecision. There are many sources of uncertainty facing the FLSs, such as uncertainties in inputs (uncertainties in the antecedent membership function); uncertainties in outputs (uncertainties in the consequent membership functions) and linguistic uncertainties as the meaning of words that are used in the antecedents and consequents.  Linguistic labels can be uncertain as words mean different things to different people. All of these uncertainties translate into uncertainties about fuzzy set membership functions. Type-1 FLCs have the common problem that they cannot fully handle the linguistic and numerical uncertainties with an unknown, uncertain and perturbed nonlinear dynamical system as they use precise type-1 fuzzy sets. The uncertainty of a given unknown system causes problems in determining the exact and precise antecedents and consequent membership functions during the FLC design, and this can cause degradation in the FLC performance. A type-2 fuzzy logic system is a system in which the antecedent or consequent membership functions are type-2 fuzzy sets. Type-2 fuzzy sets have grades of membership that are themselves fuzzy. Type-1 FLSs, whose membership functions are type-1 fuzzy sets, are unable to directly handle rule uncertainties. Type-2 FLSs are very useful in circumstances where it is difficult to determine an exact membership function for a fuzzy set; hence they are useful for incorporating rule uncertainties. 

The workshop is about the general theory of fuzzy logic and it is divided to two parts : In part A, Type 1 fuzzy logic is introduced with a simple example. In part B, the talk is about type-2 fuzzy logic.
