Modeling of linear drive for control design purposes
Drábek, Jakub ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
Thesis deals with the design of control of linear drive by taking advantage of connection between tools provided by NI LabView graphical programming environment and SolidWorks 3D CAD system. This work describes the various resources the CAD systems provide for virtual modeling of mechatronic systems and their simulation. Control is designed using simulation tools by utilizing link between NI LabView and SolidWorks, while the invented control mechanism is finally tested on real system.

Modelling of mechatronic system with flexible parts
Kšica, Filip ; Vetiška, Jan (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with the simulation modelling of mechatronic system with flexible parts using ADAMS and Matlab/Simulink. The beginning of thesis is dedicated to the summary of available methods of modelling mechatronic systems with flexible parts. Next chapters describe different approaches of modelling flexible parts using analytical and numerical methods. In the following step, model of particular mechatronic system is created. System itself consists of a flexible beam part, electromagnetic vibration exciter and vibration power generator. Each part of the system is created separately in variety of programmes, including FEMM, ADAMS and Matlab/Simulink. At the end of this thesis, co-simulation of ADAMS and Matlab/Simulink is used to describe behavior of the complete system, especially energy conversion efficiency of vibration power generator and its impact on the system.

Flood control measures in the Loučka Catchment
Hadaš, Zdeněk ; Marton, Daniel (referee) ; Starý, Miloš (advisor)
This thesis deals with the river basin flood protection Loučka. The aim to assess the need tu supplement flood control measures in the watershed. The first half deals with exploration of river basin, providing geographic factors and obtaining information on the topic. The second part deals with the establishment and application of rainfall model to solve the problem. For schematisation basin was used ArcGIS program. Rainfall simulation process were calculated critical duration of rainfall intensity and spare set of N-year flows. It was by searching for critical points and assessed for possible overflow.
