Nonlinear control of wound-rotor synchronous-motor

2006 IEEE Conference on Computer Aided Control System Design, 2006 IEEE International Conference on Control Applications, 2006 IEEE International Symposium on Intelligent Control, 2006
The problem of controlling wound rotor synchronous motors is considered. First, a nonlinear model of the controlled motor is developed in the Park (d, q)-coordinates. Then, a nonlinear regulator is designed using the backstepping technique. The resulting closed-loop is proved to be asymptotically stable and the motor speed is shown to achieve its ...

Bifurcation Analysis of the Wound Rotor Induction Motor

International Journal of Bifurcation and Chaos, 2015
This work deals with the bifurcation phenomena that occur during the open-loop operation of a single-fed three-phase wound rotor induction motor. This paper demonstrates the occurrence of saddle-node bifurcation, hysteresis, supercritical saddle-node bifurcation, cusp and Hopf bifurcation during the individual operation of this electromechanical ...

Control of wound-rotor induction motor with rotor impedance variation

Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting, 2002
It is proposed to modify the performance of a three-phase induction motor, fed from a conventional three-phase supply of constant voltage and frequency, by the use of a network of general, slip-dependent impedances connected externally into the secondary circuit, via slip rings.

Irregular windings in wound rotor induction motors

Electrical Engineering, 1934
The importance of using regular windings in polyphase wound rotor induction motors is stressed in this paper. Harmful effects upon the efficiency, power factor, breakdown torque and noise of the motor may result with an irregular winding, due to differential leakage. The Goerges diagram of tooth fluxes is presented for studying this phenomenon.

Resolver motivated sensorless rotor position estimation of wound rotor synchronous motors

2013 IEEE International Symposium on Industrial Electronics, 2013
This paper presents a novel approach to sensorless control of wound rotor synchronous motor drives. The proposed rotor position estimation strategy is motivated by principle function of a resolver and utilizes design similarity between the controlled motor and the resolver based rotor position sensor.

Superconducting wound rotor for axially excited electrical motor

Journal of Physics and Chemistry of Solids, 2006
The development of HTS motors of the fractional range has shown the relevance of the design of the rotor where the opportunity to apply HTS in both BSCCO tapes and YBCO bulks has been demonstrated as an efficient way to increase the power density. In this work we report on a BSCCO wound rotor axially excited showing the advantages over equivalent ...

Stepless starting of wound-rotor induction motors

Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1962
This paper gives experimental and calculated speed-torque-current curves for a slip-ring induction motor with an automatically controlled secondary impedance to obtain stepless starting with low current, high sustained torque, and low full-load slip. A saturable reactor in the secondary circuit is supplied with a control current from a direct-connected

Speed regulation of induction motors with wound rotor

IFAC Proceedings Volumes, 2013
Abstract The regulation of speed is required in many applications of induction motors, including in electric locomotives and electric driving vehicles. In this paper the speed control problem for a wound rotor induction motor is considered. The speed is controlled by changing the external resistance in the rotor circuit.
