Optimization in control systems
Daniel, Martin ; Václavek, Pavel (referee) ; Pohl, Lukáš (advisor)
Master’s thesis deals with using a linear matrix inequality (LMI) in control of a dynamic systems. We can define a stability of a dynamic system with a LMI. We can use a LMI for research if the poles of a system are in a given regions in the left half-plane of the complex plane with a LMI or we can use a LMI for a state feedback control. In the work we describe a desing of a controller minimizing a norm from an input to an output of the system. There is also a desing of a LQ controller with a LMI. In the end of the work, there are two examples of a design a LQ controller, which minimize the norm from the input to the output of the system and moves a poles of a dynamic system in a given regions in the complex plane, with the LMI. We use a LMI for a design a continuos LQ controller in the first example. In the second example we use a LMI for a design a discrete LQ controller.

Diagnostika traktoru Case
DOLEŽAL, David
This bachelor thesis deals mainly with Case IH tractors (hereinafter Case). It focuses on the diagnostics of the CVX continuously variable transmission, both parallel and serial. The introductory part is aimed on the theory in the field of diagnostics and its importance. The following section addresses a specific issue with a focus on the CVX continuously variable transmission. The practical part of the work first describes the simple construction of the gearbox and then the individual measurements are performed and comparisons with the prescribed values by the manufacturer.

Převodová ústrojí traktorů
Nedoma, Jan
The thesis is dedicated to currently used constructions of gear cases. It describes individual types and presents particular gear cases made by particular producers of agriculture machinery. The greatest attention is paid to the differential hydromechanical (fluent) gear case and to the mechanical gear case which is widely spread in practice. In the thesis there is also stated comparison based on various aspects: efficiency, influence on fuel consumption, lifetime, operation convenience, maintenance requirements and acquisition price. Based on findings it is obvious that the gear case powershift is suitable for tractors which carry out tractional work with static tractional load. On the contrary the differential hydromechanical gear case achieves better values at changing load, for example in traffic.
