Experimental workplace of controlled drive with high dynamics
Rozkošný, Miroslav ; Marada, Tomáš (referee) ; Němec, Zdeněk (advisor)
My diploma thesis deals with the basic principle of the frequency inverter and his construnction. In the next section are analyze the basic properties and characteristics of the using equipment. The main part of this thesis is to investigate the dynamic properties of asynchronous electric motor controlled by a frequency inverter using STARTER. The results of experiments are compared and analyzed.
Software for teaching the control of a nuclear power plant steam generator
Toman, Jiří ; Nekula, Pavel (referee) ; Němec, Zdeněk (advisor)
This diploma thesis deals with the study of steam generator regulation and development of an application, which includes a real simulation of steam generator water level control with its graphical interpretation. It presents analysis and solution in the form of software that will be a valuable application in practice. The result of the diploma thesis is educational software simulating the behavior of the steam generator level control system in referenced nuclear power plant.
Laboratory device with temperature control
Telecký, Jakub ; Škrabánek, Pavel (referee) ; Němec, Zdeněk (advisor)
This work deals with regulation and procedures that can be used for this. The theoretical part therefore presents the basic concepts of automation and controllers. The main part is the practical part. The purchased system consists of a regulated system, which must be set up correctly. Using system identification and known procedures, sample examples of how to best set the controller are compiled. The result is a sample laboratory task that automation students can try and gain experience with methods of setting up the controller.
Inverted pendulum control
Daněk, Petr ; Němec, Zdeněk (referee) ; Marada, Tomáš (advisor)
This diploma thesis deals with inverse pendulum control. There are described types of inverse pendulums, used power electronics, sensors and their connection to the MF624 control card and to external hardware. Further is described the identification of parameters, including the assembly of a custom algorithm for identification of viscous friction in the pendulum rotary coupling. For identification of moments of inertia are used 3D CAD models, where the thesis describes also use of these models for VRML visualization. The thesis also describes how to build a dynamic model by using Matlab-Simulink and the Simscape-Multibody toolbox. This model is further used in design of the controller using LQR and its simulation testing. The controller is complemented by swing-up algorithm, security elements and MF624 driver interface is designed. The control is tested on a real inverse pendulum assembly and implemented in external hardware.
Temperature control und monitoring of laboratory kiln
Dvořák, Pavel ; Marada, Tomáš (referee) ; Němec, Zdeněk (advisor)
The aim of this bachelor work is to create a laboratory training which is made for teaching and demonstration laboratory furnace temperature control with applications created in Control Web 6.1 The role includes the regulation and capture waveforms measured and desired temperatures, allows the timing of the required temperature. The application is processed for example burning of small products. Allows archiving of temperature distribution and also monitoring the instantaneous values of the desired and measured temperatures with the possibility of switching heating via the Internet. The thesis presents a proposal for linking laboratory furnace with a computer using the input output module DataLab
Examples of governings with predictive controls
Šalda, Zbyněk ; Švarc, Ivan (referee) ; Němec, Zdeněk (advisor)
This thesis deals with model predictive control principally Based Predictive Control (MPC). The first part describes the principle of predictive control, cost function, the choice of a constraints in regulation and the choice of weights. In the next section is an analysis system: a system with non-minimal phase (control water turbine), oscillating systems (trolley frame control) and system with a time-delay . In all of these systems is performed classical feedback control using PID control and concurrently regulation with the MPC. MPC is selected as the solution fy Mathworks Model Predictive Control Toolbox and Simulink. The results are then analyzed using the criteria of quality control.
Heating system model
Kintr, Michal ; Němec, Zdeněk (referee) ; Marada, Tomáš (advisor)
The goal of this work is to project and implement a simple model of a heat system. The system is controlled by a suitable PLC (Programmable Logic Controller). The heat system model is realized in order to be the helping instrument for teaching programmable automatics. The design and construction of the heat system model as well as the choice of a suitable PLC is fully described in this thesis.
Examples of drive control with frequency convertor Sinamics S120
Novák, Michal ; Marada, Tomáš (referee) ; Němec, Zdeněk (advisor)
In this thesis is described a laboratory process of example of traction control with frequency converter SINAMICS S120. The focus of this thesis is divided into three parts. Modification of the traction to translational motion for transport of the open vessel with liquid. Proposal of the autonomous operation of the traction without connection to other devices such as a personal computer or PLC, including wiring diagram. The simulation of a dynamic movement for transport of the vessel with liquid in the simulation environment MATLAB and implementation using the proposed laboratory traction. Commissioning and activation of each control functions is described step by step.
Accumulator charging proceedings with detailed evaluation
Pálka, Antonín ; Marada, Tomáš (referee) ; Němec, Zdeněk (advisor)
The purpose of this work is to propose a preparation for charging and discharging of accumulators. This preparation is suitable for demonstration of charging and discharging cycle of hermetical accumulators in teaching Electrotechnics, Physics and possibly Chemistry. For this charging and discharging I created user's assistance program with the help of visual system Control Web 5 with moduli of the contact DataLab and with the option of variants. Graphic expressions of the results are preferred in the form of time records.
Drilling CNC machine
Drlík, Michal ; Němec, Zdeněk (referee) ; Marada, Tomáš (advisor)
This thesis deals with designing and realization of a CNC drill. The body of the thesis is divided into three parts: Firstly, a design of a mechanical construction, secondly, an electronic scheme with its realization using industrial components and lastly, a design of a data export from an application for DPS EAGLE designing to G-KOD formate. The whole process should make drilling of plates with DPS or eventually the whole plate manufacturing more efficient and the quality and accurancy of a whole work should increase.
