This paper presents a new approach on the plant augmentation and target feedback loop parameterization for the discrete-time LQG/LTR control. With the proposed procedure, the bound on the sensitivity of the control loop can be associated with the behavior of the inverse of any real stable pole, ensuring good properties of disturbance rejection and tracking of reference signals in situations where...
This paper deals with the small-signal stability analysis of a dc-distribution electrical power system (EPS) sourced by permanent-magnet synchronous generator (PMSG), which is one of the main topology candidate for future more-electric aircraft (MEA). A detailed mathematical model is developed and comprehensive EPS modal analysis including eigenvalues sensitivity and participation factor performed...
In this paper, we propose an overview of the Fault Detection and Diagnosis concept as the detection and characterisation of a hidden information as usually addressed in Data Hiding approaches. In fact, on one side Fault Detection and Diagnosis is generally studied as the detection and characterization of changes (abrupt or not) in a signal describing the behavior of a system. On the other side, data-hiding...
Most statistics for fault detection in engineering systems are designed to detect shifts in the process distribution parameters, such as mean or variance shifts. The incipient fault is, however, more likely to affect the probability distributions in an unpredictable (random) manner. It causes slight distortions along the distribution shape rather than a particular parametric change. In this paper,...
