Multiloop dynamical models of human driver
Čelko, Jakub ; Jirgl, Miroslav (oponent) ; Mihálik, Ondrej (vedoucí práce)
The thesis is focused on modelling human-machine systems, where a human operator controls a vehicle. The result of the work is a comparison of the prediction capabilities of chosen multiloop and single-loop human driver models. These models are applied in scenarios where, in addition to the lane change forcing function, there is also a disturbance signal that affects the vehicle’s motion. The parameters characterising the human dynamics are extracted from the model of the whole loop, defined as a discrete state-space model. The thesis also contains research on driver models, description of the used vehicle simulator and the Unreal Engine 4 environment used for its implementation. Documentation of implemented disturbance signals that act as a fault at the input of the regulated system is also presented. The identification results on the measured data suggest that the models relying on a single transfer function are losing prediction capabilities in scenarios, where the disturbances affect the vehicle. In such cases, the multiloop models with the same number of parameters are able to capture human behaviour more accurately.

McRuer Models for Human-Machine Systems
Čelko, Jakub ; Jirgl, Miroslav (oponent) ; Mihálik, Ondrej (vedoucí práce)
Bachelor’s thesis is focused on modelling of the human-machine systems using McRuer models, particularly systems formed by human operator and a steering wheel. The aim of the work is to design and measure the responses of the human operator in the regulation of different types of systems and different system forcing functions. Different steering wheel stiffness was also measured to find its influence on the speed and quality of the regulation. Results of this work are mathematical descriptions of the operator for the individual scenarios. The descriptions are expressed as transfer functions, with the operator being considered as linear time-invariant system.
