Design and Implementation of Algorithms for Compensating the Effect of Linear Acceleration on Angular Velocity Measurements by MEMS Gyroscopes
Spáčil, Tomáš ; Luczak, Sergiusz (oponent) ; Hnidka, Jakub (oponent) ; Grepl, Robert (vedoucí práce)
This Dissertation deals with the development of a new type of forward compensator, specifically designed to counteract the effect of linear acceleration and jerk acting on MEMS gyro sensors. From the principle of inertial sensor function, additional undesirable forces (normal and tangential) occur when the gyro sensor is placed off the axis of rotation, which negatively affect the measurement of the desired angular velocity. However, the presence of these forces can be measured by an independent sensor, the accelerometer, and the output value of the gyro sensor can be compensated for in a suitable way, thus refining the indirectly measured value of the angular velocity. In the first part of the paper we identify the effect of the mentioned accelerations on MEMS gyroscopes, in the second part of the paper we design and test different compensators, evaluate their effectiveness and in the third part we implement a suitable algorithm on RT HW.

Verification of rotor model properties for sleeve bearings
Šály, Timotej ; Hnidka, Jakub (oponent) ; Klusáček, Stanislav (vedoucí práce)
This bachelor thesis deals with a professional research in the field of sleeve bearings and their diagnostic disorders. It describes the recognized methods of identification and technical diagnosis of these errors. Furthermore, it describes the features and possibilities provided by the rotor model RK4 in the simulation of sleeve bearings. Moreover, the thesis deals with the development of a laboratory task for students to demonstrate the diagnostic fault of oil whirl.
