In this paper, the problem of fault detection under disturbances for multi-input and multi output linear systems is investigated. The considered fault detection approach relies on the recently developed PI observer. A new algorithm is proposed to calculate the gain of the PI observer with the purpose of optimizing the fault detection performance. In the proposed approach, part of the gain matrix is...
The objective of this study is to model the attenuation of ultrasonic waves as they propagate through the trabecular bone. Trabecular bone is assumed to be constituted of a binary mixture of a bone matrix and a saturating fluid (marrow or water). The disturbances to which it is subjected are supposed to be of low amplitude. The attenuation due to absorption is determined by using the analytical model...
A communication satellites play a large role in the socio-economic development of a country, however the satellite communication system design trade-offs increase with the complexity of the payload requirements. For reliable and dynamic in-orbit satellite operations, the payload receiver must have the capability to adapt to emergent mission and postmission application requirements. The communication...
