This chronic syndrome associates with a low functional status and quality of life. Most patients with HF are elderly, constituting up to 80% of patients suffering from this disease with both incidence and prevalence of the condition increasing with age. This is due to the progressive aging of the population as well as improved and better survival after cardiac insults, such as myocardial infarction,展开更多

Conditions for the existence of such a fault detection observer are given in terms of matrix inequalities. The solution is obtained by new iterative linear matrix inequality （ILMI） algorithms. The RFD observer design over finite frequency range in which Of does not have full column rank for a system is also considered. Numerical example demonstrates that the designed fault detection observer has high sensitivity to the fault and strong robustness to the unknown input.展开更多
