Design and realization of measuring device for determination of human arm force depending on elbow joint angle.
Zezula, Miroslav ; Vlk, Miloš (referee) ; Krejsa, Jiří (advisor)
The goal of this bachelor’s thesis is design and realization of measuring device for determination of human arm force depending on elbow joint angle. Used measuring method allows to measure this relationship during one continuos movement from one limit position to another. Simplicity of single measurement run allows to obtain a large set of values and evaluate it statistically. This thesis contains a detailed technical description of the measuring device. Actual force and position of hand are measured by electric transducers. Measured values are captured using Spider8 data acquisition system. Based on experiences from first test measurement, the measuring device is modified and drive unit is added. This drive unit is automatically started by a signal from data acquisition system.

Implementation of methods for measurement of rotational speed using cRIO platform
Fábry, Tomáš ; Uher, Miroslav (referee) ; Havlíková, Marie (advisor)
This diploma thesis implements methods for a measurement of rotational speed. It is implemented on the Compact RIO platform from National Instruments. Corresponding SW is implemented using the graphical programming language G in LabView environment. Developed system uses two different sensors – incremental encoder and tacho sensor for measurements of rotational speed. Thesis further analysis and implements a method for an encoder nonlinearity determination and for its on-line correction. For used methods, effects adding errors into the measurements are evaluated and quantified.

Digital volume control pod with graphic display
Schilhab, Karel ; Balík, Miroslav (referee) ; Hanák, Pavel (advisor)
The bachelor thesis deals with the design and construction of a digital volume control with graphical indication, Mute and Standby functions. The design includes a microcontroller, OLED display, D / A converter, incremental encoder and voltage stabilizer. Communication in the device takes place via the I2C line. Stopping the volume is realized by changing the voltage in the range from 0 to 1 V. The aim of the work is to design and manufacture the circuit, write the source code and build the device into the box.

Helicopter model control
Štefanisko, Ivan ; Blaha, Petr (referee) ; Pohl, Lukáš (advisor)
In this paper we will introduce the existing model of a helicopter for teaching dynamic systems. Later, we will explore various control options of a model, and design laboratory tasks for the selected subject for bachelor‘s and master‘s study. In becoming acquainted with the model of a helicopter we describe hardware parts and the theoretical mathematical model. We can design controls after we have created a subprograms aimed at raising the rotational angle arms, pulse-width modulation to control the motor speed or creation itself control. The control methods we propose are the Ziegler-Nichols and frequency characteristics. The actual laboratory tasks will be formed with respect to the content of subjects taught bachelor‘s and master‘s study.

PLC Control of Robotic Manipulator
Krajcar, Tomáš ; Svoboda, Jakub (referee) ; Hynčica, Ondřej (advisor)
The thesis is focused on the design control of a 3-axis robotic manipulator. The manipulator is used for transporting the moulded part from a moulding machine to a conveyor belt. A manipulator has 3 asynchronous motors controlled by one frequency changer. A PLC is designed for full control of this operation. A PLC uses a real time operating system, which allows it to work on several tasks at the same time. A PLC has Modbus TCP/IP communication with HMI. A PLC has Modbus TCP/IP communication with HMI. A manipulator communicates with a moulding machine via a EUROMAP 12 interface.

Modelling, Optimization and Control Design for Strongly Nonlinear Systems with Discrete Sensors
Bastl, Michal ; Štefek, Alexandr (referee) ; Opluštil, Vladimír (referee) ; Grepl, Robert (advisor)
The main motivation for this effort was international cooperation on modeling and control design for the stabilization system of the naval satcom antenna. The dissertation focuses on the design of models based on ODE and DAE from the perspective of mechatronic design. It mainly discusses the possibilities for simulation with a fixed step solvers, what is a necessary condition for real-time simulation and other use of modern approaches such as RCP and HIL. Furthermore, the work deals with modeling of friction, which is due to the strongly non-linear properties problematic for numerical models. The last output is the simulation comparison and verification of the possibility of implementing the incremental encoder into the Kalman filter algorithm.
