Adaptive Decoupling Control of Induction Motor Drives

Proceedings.14 Annual Conference of Industrial Electronics Society, 1990
A novel control approach for a robust induction motor drive system with a voltage source inverter has been developed. In the scheme, the induction motor and its corresponding inverter gating signal are controlled using the decoupling control theory. In addition, an adaptive optimal speed regulator employing the model reference adaptive control (MRAC ...

Adaptive Vector Control of Induction Motor Drive

2020 7th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE), 2019
Modern induction electric drives usually use vector control, due to which their characteristics are improved. The purpose of most studies are the problems associated with the identification and estimation of the parameters of electric drives at zero speed and close to it. The article proposes an adaptive control in the control loop of the torque.

Adaptive Learning Control for Induction Motor Servo Drives

2007 IEEE International Symposium on Industrial Electronics, 2007
The output feedback tracking control problem for induction motor servo drives with mechanical uncertainties is addressed. Under the assumption that the reference profile for the rotor angle is periodic with known period, an adaptive learning control is designed, which "learns" the non-structured unknown periodic disturbance signal due to mechanical ...

Matrix Converter Induction Motor Drive

2006 12th International Power Electronics and Motion Control Conference, 2006
The presented paper deals with the matrix converter induction motor drive with emphasis on the PWM modulation strategies design. Matrix converters provide an all-silicon solution to the problem of converting AC power from one frequency to another, offering almost all the features required of an ideal static frequency changer.

Invertor drives for induction motors

Students Quarterly Journal, 1972
Induction motors have many advantages for industrial use, but the only simple and efficient way of controlling their speed is by using static invertors to supply them with variable-frequency, variable-voltage a.c.

Large Induction Motor Drive Performance Comparison

2018 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC), 2018
Comparative analysis of the performance of a motor drive with different controller strategies such as Volt-age/frequency (V/F), Proportional, Integral (PI), and Neural Network (NN) controllers to follow speed and torque variations is presented. Bezier profiles are used to reduce peaks in voltage an current when the motor conditions change.

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 ...
