Alternative control SW for dedicated thermal performance chambers with customized UI
Žlebek, Jan ; Veselý, Libor (referee) ; Václavek, Pavel (advisor)
This thesis is oriented on simulating thermal chambers, their SW and HW and improving SW to meet specifications. Testing problematics connected with this thesis is briefly mentioned also. Thermal chambers used here are dedicated to run simulating test procedures for thermostats and similar devices designed to sense temperature and regulate it. Design and realisation of new SW are clarified in latter chapters of this thesis, as well as evaluating functionality and resulting dynamics and accuracy.

Closed loop system identification
Piskoř, Dominik ; Buchta, Luděk (referee) ; Pohl, Lukáš (advisor)
This thesis deals with testing of various modifications of the least-squares method, which reduces the bias in system parameter estimation. The first part of this thesis is focused on the theory and principles of every single method. The second part describes the implementation of identification methods in Matlab and Simulink. The third part is focused on the evaluation of used methods via statistical analysis. This part also contains an identification of electric parameters of the real PMSM motor model.

Řízení krokového motoru v částečně uzavřené smyčce
VEBER, Jan
The goal of this bachelor thesis is to clarify drivers basic of electric driver to students interrested in motion and some extended methods of control stepper motors with microcontroller. This thesis should explain principles of stepper motor, kinds of motion profiles, their properties, advantages, disadvantages and also methods their computations. Second goal is to explain the fieldbus protocol MODBUS and its implementation into PIC32 microcontroller. Practical part of this thesis is design and construction of a demonstration kit which allows to students see and better understand basic of stepper motor control and its integration to master system via MODBUS. Benefit of this thesis is that it introduce nowadays methods of control stepper motors to student to get view of industry implementation as well as control systems via fieldbuses/networks. The demonstration kit helps to achieve this goal. It was designed to be crash resistant, easy control and safe for users. The demonstration kit could be controlled by a third party device because of its modularity. Moreover the kit should be controlled by a PC software via MODBUS.
