Implementation of a vector controlled induction motor drive
Acar, Akın; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2004)
High dynamic performance, which is obtained from dc motors, became achievable from induction motors with the recent advances in power semiconductors, digital signal processors and development in control techniques. By using field oriented control, torque and flux of the induction motors can be controlled independently as in dc motors. The control performance of field oriented induction motor drive greatly depends on the correct stator flux estimation. In this thesis voltage model is used for the flux estima...
State estimation techniques for speed sensorless field oriented control of induction motors
Akın, Bilal; Ersak, Aydın; Department of Electrical and Electronics Engineering (2003)
This thesis presents different state estimation techniques for speed sensorlees field oriented control of induction motors. The theoretical basis of each algorithm is explained in detail and its performance is tested with simulations and experiments individually. First, a stochastical nonlinear state estimator, Extended Kalman Filter (EKF) is presented. The motor model designed for EKF application involves rotor speed, dq-axis rotor fluxes and dq-axis stator currents. Thus, using this observer the rotor spe...
Development of a computer program for friction winding system design
Ünal, Fuat Gökhan; Bölükbaşı, Naci; Department of Mining Engineering (2011)
As the trend to deeper mines continues, mine hoists and associated equipment will become more sophisticated, complex, large and expensive. Correct selection of the right type of hoist is imperative. In this vital link between underground and surface, crude estimates of hoist capacity are not good enough, and the mining engineer must design and select the right hoisting system to meet the design specifications and establish the most suitable operating parameters. This study aims to constitute a software mode...

The first part of this two-part paper described the starting transients of a slip energy recovery IM drive using the rotor rectifier and a single resistor instead of three resistors and an ac circuit breaker. The starting transient was divided into three stages; the first was the resistance starting, the second was the connection of the inverter and the third was the disconnection of the starting resistor. The diode bridge rectifier imposes constraints onto the machine equations; the relevant equations fo...
