A state-space representation of the knee joint model of the paraplegic patient with its nonlinearity is also demonstrated. The use of linear matrix inequalities (LMIs) in control systems with norm-bounded uncertainties for asymptotic stability is analyzed. The model was simulated in the Matlab environment. The matrix K of state space feedback was obtained through LMIs.engArtigo10.1155/2015/736246Acesso aberto2-s2.0-849411128122-s2.0-84941112812.pdf8630973561889272887996458277884050620873805714620000-0002-1072-3814
