Adaptive Damping for Trucks
Neuman, Ondřej ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis is concerned with designing a computational model of a commercial vehicle. In addition to that, a control algorithm for adaptive damping is presented. These two parts are connected into a closed loop and together they create an adaptive damping system. The primary task of the algorithm is to react on a vehicle load change. Vehicle model has the opportunity to create different driving scenarios, which are used to verify algorithm functionality. With the help of computational model and optimalization process, suitable damping characteristics are derived. An evaluation of vehicle comfort and driving safety is also presented.

Adaptive control of magnetorheological dampers
Míša, Jiří ; Porteš, Petr (referee) ; Zháňal, Lubor (advisor)
The topic of this master´s thesis is the design of adaptive damping algorithm for the prototype magnetorheological dampers, which are used for Formula Student vehicle. The prime output is the development and optimization of the control algorithm which included usage of the MBS software and real data from race track. Temperature compensation to supress the effect of dynamic viscosity of magnetorheological fluid due to the increase in operating temperature and testing of the vertical dynamic of the car on 4 - post test rig was realized as well. The main goal was to obtain better control of the car in transient situations and increase usability of tires via changes in damping based on actual conditions and status of the vehicle.

Development of control electronics for magnetorheological dampers in Formula Student vehicle
Skřivánek, Vladimír ; Dobossy, Barnabás (referee) ; Adámek, Roman (advisor)
The topic of this bachelor thesis is the design of a control board for magnetorheological dampers. The board has to be able to receive input data from a datalogger over the CAN bus. From these data, it has to calculate the required current using a known control algorithm and has to be able to regulate it by feedback using a PI controller. Furthermore, it should be able to measure the temperature of the magnetorheological fluid in the damper to be able to correct the degradation of the damping force due to increasing temperature. Another part of this work is to test the implementation of this control algorithm and measure the F-v characteristics of the magnetorheological damper for different values of current.
