Autor: Ki-Ryeok Yong, Sangkyung Sung, Young Jae Lee, Sang-Jun Park

Publikováno v: Journal of Institute of Control, Robotics and Systems. 18:546-554

This paper suggests a design method of an improved phase control loop for tracking resonant frequency of solid type precision resonant gyroscope. In general, a low cost MEMS gyroscope adapts the automatic gain control loops by taking a velocity feedb

Fault Detection of a Spacecraft's Reaction Wheels by Extended Unknown Input Observer

Autor: Ki-Ryeok Yong, Jae-Hyun Jin

Publikováno v: Journal of Institute of Control, Robotics and Systems. 17:1138-1144

This article deals with the problem of fault detection of a spacecraft`s actuators. The authors introduce an extended unknown input observer for nonlinear systems. This is an extended form of unknown input observers which are used for linear systems.
