Sensorless position control of solenoid valve
Keprt, Jaroslav ; Janák, Luděk (referee) ; Houška, Pavel (advisor)
This thesis deals with the determination of the position of the solenoid core in real time based on the measured current. The reference position of the current is used for feedback control of the solenoid. For this issue, software tool Matlab/Simulink was used. For current and temperature measurements, PCB circuits were created. The whole project was carried out on the dSPACE platform.

Sensorless position control of solenoid valve
Piňos, Matěj ; Chalupa, Jan (referee) ; Grepl, Robert (advisor)
This thesis deals with position control of movable solenoid core without using a distance sensor. There are several methods of sensorless position estimation presented in theoretical part. The method based on measurement of ripple current is chosen for experiments. Firstly, it is verified by simulations with mathematical model of solenoid. After that, the experiment is created. The goal is position control based on sensorless method.

Dynamic analysis and prototyping of coilgun
Militký, Ondřej ; Musil, Filip (referee) ; Rubeš, Ondřej (advisor)
This thesis deals with the description of the Gaussian rifle principle. It describes the physical principle, on which the device works, the design of the structure and its advantages and limitations. Furthermore, a computational model is created in the Matlab Simulink environment, which simulates the behavior of a projectile during a shot. Based on this model, a prototype Gaussian rifle is designed and constructed. The prototype is then tested and compared with a computational model to determine the overall effectiveness of the created rifle.

Programmable Thermoregulator Design
Kollár, Tomáš ; Steinbauer, Miloslav (referee) ; Hermany, Jiří (advisor)
The aim of the study was to design, build and experimentally verify a programmable thermostat. The main control unit of the thermostat is an ATmega168 microcontroller which communicates via I2C bus with remote MAX6615 chips. They are used to measure temperature with a set of thermistors and control the flow of the hot water in the heating system. This work deals with issues of remote control through the I2C bus, servomotor steering, precision temperature measurement and describes the inner workings of the system. The next chapter includes a proposal for possible extension of the system. The last part contains the manual of the control menu structure and a brief description of the software.

Fluxmeter with graphical display of B-H curve
Ježek, Jaroslav ; Mačák, Jaromír (referee) ; Hanák, Pavel (advisor)
This work deals with simple fluxmeter which is able, together with other device, to show hysteresis loop. Hysteresis loop is a graphic expression of dependence of magnetic induction on intensity of magnetic field. Oscilloscope is used to display the hysteresis loop. This device is fully sufficient for the display. The measured objects are solenoids from various kinds of materials with the same shape. The main aim of this work is the design, realization and description of the fluxmeter. The fluxmeter consists of several partial blocks. The first one, on which this work is focused, is signal generator which is able to generace different kinds of signal. The generated signal comes on primary winding of solenoid where a magnetic field on a given intensity rises. An amplifier is used to obtain the sufficient intensity. Next thing this work is focused on is the design of the integrator which is necessary for the correct function of the fluxmeter. As suggested, there is shown the block diagram of linking of individual parts. There are described the measured results at the end of this work.
