Parameter Sensitivity in Sensorless Induction Motor Drives With the Adaptive Full-Order Observer

IEEE transactions on industrial electronics (1982. Print), 2015
Parameter mismatches seriously impact the stability and the rotor-speed accuracy in sensorless induction motor drives, particularly in low speed. To deal with the parameter sensitivity of the drive system with an adaptive full-order observer (AFO), this ...

Transistor-oscillator induction-motor drive

Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1958
Transistor and saturable-core-transformer oscillators driving small 2-phase induction motors provide, in effect, a d-c motor without a commutator. The inductive, motor load on the oscillators requires that the transistors carry current in both directions and this is aided by shunting the transistors with rectifiers.

Induction motors for synchronized drives

Electrical Engineering, 1949
THERE are two types of synchronized drives of two or more mechanically independent shafts commonly known: one is the “power selsyn” or “synchro-tie;” and the other might be called the “simplified selsyn.” The first system uses, besides one or more prime movers, individual selsyn motors for synchronizing.

Induction motor drive with matrix converter

Proceedings of 1995 International Conference on Power Electronics and Drive Systems. PEDS 95, 2002
Control methods of the three-phase induction motor supplied by 3, 6, 9, ... phase matrix converters are investigated by means of using Park-vector representation. The motor voltage is only constructed from the possible rotated and zero value voltage vectors. It is shown that motor harmonic losses and torque pulsations can be kept at low values with the

Concatenated induction motors for rolling mill drive

Proceedings of the American Institute of Electrical Engineers, 1914
The paper describes a six-speed concatenated induction motor set for driving the finishing rolls of a 12-stand continuous mill. Analysis of the conditions in this mill showed that the use of a low-pressure turbine would lead to the waste of a large amount of exhaust steam and that the alternating-current turbine plant which was in operation had ample ...

Control of Induction Motor Drives

1985
When comparing the dynamic model of a separately excited DC machine, Eqs. (5.1–5.4), Fig. 5.4, with that of an AC induction machine, Eqs. (10.38–10.41), Fig. 10.16, it is obvious that the latter represents a much more complex control plant. This is caused by the fact that the main flux and the armature current distribution of a DC machine are fixed in ...
