Design of indirect sensing of gas valve throttle position
Burian, Jaroslav ; Jankovský, Jaroslav (referee) ; Otáhal, Alexandr (advisor)
This thesis deals with the design of a circuit for measuring the throttle position of the PX52 valve from Resideo. The theoretical part discusses the methods whose principle can be used to determine the position of the throttle valve controlled by a stepper motor. Subsequently, the communication protocols that can be chosen between in the design are described. Methods for measuring the mutual properties of the coils were also described. In the practical part, a PCB was created to verify both methods. Furthermore, a program for testing both methods is described in the paper. These methods are compared with each other for different coil variants. Finally, the method is selected and the program is modified for the measurements.

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].

Flexible textile-integrated coils for inductive energy transfer
Konečný, František ; Cupal, Miroslav (referee) ; Raida, Zbyněk (advisor)
This work aims to describe the design of flexible textile coils in several variants (different coil dimensions, different designs). The parameters of the designed coils will be verified using simplified simulation models and compared with theoretical calculations. Further, the work deals with the practical design of coils, including the measurement of their basic parameters and determination the efficiency of inductive power transfer.
