In this study, a structure of a five degree of freedom flywheel energy storage system (FESS) is introduced. A nonlinear model of active magnetic bearing (AMB) system in the FESS is obtained by Lagrange's equation. In this model, the current in each coil is treated as a state variable and the control input is the voltage applied to each coil, this approach(More)
The purpose of camera calibration is to reconstruct the world coordinate system using two-dimensional images. A good calibration result depends on identifying the camera parameters successfully. The use of single two-dimensional calibration boards or three-dimensional calibration boxes for camera calibration results in a camera model which is suitable for(More)
