Multiaxis feedback cooling of particle in optical trap
Číž, Adam ; Adámek, Roman (referee) ; Brablc, Martin (advisor)
This thesis deals with a design and implementation of algorithms for multiaxis feedback cooling (which means positional control) of a particle in an optical trap with use of Kalman filter. Two control methods are proposed here, each of which is intended for use of a different actuator: a laser intensity modulator or a pair of electrodes. Next, the implementation of both methods on hardware with an FPGA is described. Functioning of both proposed algorithms is proven by a numerical simulation. In addition, the functioning of the control using electrodes is demonstrated by an experiment with an optical trap. The second method is fully prepared for use in an experiment.
Modelování chůze čtyřnohého robotu
Číž, Adam ; Křivánek, Václav (referee) ; Grepl, Robert (advisor)
This thesis deals with creation of a dynamic model of a walking quadruped robot in MATLAB/Simscape Multibody environment. It describes the process of creation from modelling of the geometry all the way to the gait algorithm assembly. Inverse kinematics was used to create the gait algorithm. The thesis also includes evaluation of the outputs of the model in form of angular velocity and torque time course in the joints of the robot while walking.
