Stabilization of sensorless induction motor drives: A survey
2013 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD), 2013This paper presents a survey of methods for stabilization of sensorless induction motor drives. Some frequently suggested flux and speed estimators - such as full- and reduced-order observers - are reviewed, along with their key properties. Three commonly occurring instability phenomena are discussed, as are methods for preventing them. The methods are

Adaptive Decoupling Control of Induction Motor Drives
Proceedings.14 Annual Conference of Industrial Electronics Society, 1990A 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 ...

Invertor drives for induction motors
Students Quarterly Journal, 1972Induction 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.

With more than 85% of electrical motors, induction motors (IMs) dominate the market for electrical motors and consume more than 60% of total industrial electricity across the globe [1]. Their extensive use is a result of their strong low-cost design along with their reliability and cheap maintenance.

Induction motors for synchronized drives
Electrical Engineering, 1949THERE 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.

Voltage vectorial control of an induction motor drive
IEEE International Symposium on Industrial Electronics. Proceedings. ISIE'98 (Cat. No.98TH8357), 2002The paper describes a vectorial control strategy for induction motor fed by VSI which allows to exploit the dynamic performances by taking into account both the rotor and stator time constant, and avoiding at the same time the use of current control loop.

This section deals with the general description of induction machine drives including general properties and applications. The principle of the dc equivalent for the induction machine has been developed with interest in torque and flux control. Then, the control implementation has been suggested on the basis of the simple Stanley equations for the ...

Sensorless speed control in induction motor drives
Proceedings First IEEE International Workshop on Electronic Design, Test and Applications '2002, 2003This paper describes a method of sensorless speed estimation that is low cost and easy to implement. It uses two different algorithms, and so compensates for the weaknesses of the individual algorithms producing a robust low cost application. A method is investigated that uses the rotor slot harmonics to estimate the speed of the motor above 300 rpm ...

This chapter explores the use of induction machines in variable speed drive systems by using several control strategies. First, voltshperhhertz control, is designed to accommodate variablehspeed commands by using the inverter to apply a voltage of correct magnitude and frequency so as to approximately achieve the commanded speed without the use of ...

Flywheel-induction-motor drive
Electrical Engineering, 1950MANY DRIVES with fluctuating loads must be equipped with flywheels in order to reduce the size of the motor required and the load peaks taken from the supply mains. This problem has been discussed in many papers and technical books, and it is obvious that the general-purpose induction motor cannot be used for flywheel drives.
