Identification of AC induction motor parameters
Křížek, Tomáš ; Václavek, Pavel (referee) ; Blaha, Petr (advisor)
This thesis describes and realizes (in program Matlab/Simulink and in the microcontroller Freescale 56F8346) one off-line identification method of AC Induction motor parameters which are necessary to implement the field-oriented control strategy. The identification metod identify leakage inductance, magnetizing inductance and secondary time constants. The presented method is evaluted, advantages and disadvantages of this method are evaluated with reference to their possible use in real-machine. The experimental results and schemes which are presented demonstrate the feasibility methods. The thesis is dividend in seven chapters. Second chapter describes the basic principle and model AC induction motor. Third chapter generally describes identification methods. Fourth, fifth and sixth chapters deal with method which is based on a previous work of the authors [4] and [5].

Optimalization of Parameters of Asynchronous Motor
Hussain Mohammed, Mohammed ; Singule, Vladislav (referee) ; Voženílek, Petr (referee) ; Ondrůšek, Čestmír (advisor)
The doctoral thesis is divided into two main parts.The first part deals with optimalization of the equivalent circuit parameters of induction motor for calculation steady state characteristics:- - of the equivalent circuit parameters of induction motor with normal slots. - of the equivalent circuit parameters of induction motor with deep slots. -simulation of selected chracteristics and comparison with measured values. The second part of this work deals with optimalization of the equivalent circuit parameters of induction motor for calculation of dynamic characteristics of induction motor –simulation of selected chracteristics and comparison with measured values. The optimalization is based on mutual comparison of measured and calculated torque-speed and current-speed characteristics.
