Design and implementation of a CANopen communication unit
Řehák, Tomáš ; Kovář, Jiří (referee) ; Houška, Pavel (advisor)
This diploma thesis describes the design and implementation of an industrial communicator for synchronization and control of electrical drive controllers with the interface of RS232 or CANopen. Hardware of communicator uses the EMX development system by GHI Electronics. Communicator software is implemented in C# by the .NET Micro Framework. Communicator allows user to adjust and control up to four electric motor drives. After a successful connection with each unit, communicator can control its position, which specify the number of revolutions to the nearest thousandth of a turn. Communicator also periodically finds out and displays the current position of the connected units. User operates the communicator with GUI, application instructions are entered via the touch screen or buttons.

Control of linear drive HIWIN by NI SoftMotion
Sabó, Marek ; Šubrt, Kamil (referee) ; Houška, Pavel (advisor)
This thesis deals with the control of HIWIN three-phase linear synchronous motor using NI SoftMotion and frequency inverter D1-N on the NI Compact RIO platform. In the introductory section is discussed the classification of linear motors, the principle of functionality of linear synchronous motors, described the fieldbus EtherCAT and the NI SoftMotion module. Further work is dedicated to the hardware used, its parameter, configuration and the regulation of drive control. The final part focuses on the design and implementation of axis control and movement accuracy verification.

Implementation and analysis of control circuits in MATLAB/Simulink
Hanuš, Tomáš ; Houška, Pavel (referee) ; Singule, Vladislav (advisor)
The thesis is focused on comparing the characteristics of the most common types of controllers. This comparison is done in MATLAB / Simulink to model the DC motor. First, in the thesis, theoretical description of all structures controllers that are tested. This is specifically the PID controllers, PSD, PI-D, PS-D, S-PD, I-PD, PID filtering of derivative and PSD also with this filtration. Then there is the function given the DC motor and its mathematical description. In the last section of the theoretical part describes the different methods of setting regulators. In conclusion, this thesis compares the structure of individual regulators. There are the results. A comparison of their behavior with position control of DC motor.

Realisation of the laboratory test instrument hardware for active magnetic bearing
Petrušek, Marek ; Turek, Milan (referee) ; Houška, Pavel (advisor)
The work is focused on the designing the active magnetic bearing and the construction of its fixing system. Hardware is designed to control the active magnetic bearing; it measures the rotation speed and does the following processing. The sensors produce the information about the magnetic bearing rotor location. The next part was dedicated to the development, which has been done in this field of interest. The used parts were mentioned with their characteristics and the function of power blocks was discussed. In the practical part, the realization of this magnetic bearing and the measurement of its location, power blocks and hardware behavior in the real design are described. The last part summarize all the work that was done.

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.

Control of linear drives HIWIN
Roman, Jan ; Kaván, Martin (referee) ; Houška, Pavel (advisor)
The diploma thesis deals with three phase linear synchronous electric motors mounted on linear drive, its system of sensors and control. The analysis of working principle and classification of linear motor was done in the beginning part; analysis of the drives sensors system was made in the following chapter. The thesis also deals with the driver from the automation point of view, its tuning and behavior according to high dynamics and precise positioning. The last chapter discusses the issue of controlling two linear drives. Whole thesis was realized on a borrowed linear motor with driver from HIWIN corp.

Energy efficient hydraulic system design for force loading of vehicle drivetrain systems
Robenek, Vít ; Ožana, Otakar (referee) ; Houška, Pavel (advisor)
The thesis focuses on a hydraulic system design for a specific application of hydrostatic drive with regard to energy efficiency of proposed solution. Standard hydraulic and electronic components are used, mostly products of Bosch Rexroth. The aim of the thesis is to carry out a complex design from mechanic through hydraulic up to the electronic part of the system. After a short introduction in the beginning of the thesis is the particular application described and analyzed. Then the elemental principles of hydraulic devices and systems are explained. In the following part the actual solution is presented, which expands to several different alternatives. These alternatives are compared according to set criteria and the selected alternative is then further developed. At the end of the thesis, the outputs are evaluated and the direction of further possible improvements in the design is outlined.

Using NI SoftMotion for control of multi-axis manipulators
Staňo, Martin ; Šubrt, Kamil (referee) ; Houška, Pavel (advisor)
The purpose of the thesis is to become familiar with the issue of motion control systems, to acquaint with the NI SoftMotion module and after that use it to create an application for control of the multi-axis manipulator. The algorithm of control is solved analytically and numerically by terms of forward and inverse kinematics. The result of the thesis is the motion application of software NI SoftMotion, which is a part of a simulated virtual model of three-axis manipulator and in consequence the software is used on real hardware.
