Acesso:.https://repositorio.ufpa.br/handle/2011/7178In this thesis is presented a neural-genetic model, oriented to state space controllers synthesis, based on the Linear Quadratic Regulator design, for eigenstructure assignment of multivariable dynamic systems. The neural-genetic model represents a fusion of a genetic algorithm and a recurrent neural network to perform the weighting matrices selection and the algebraic Riccati equation solution, respectively. In order to a assess the LQR design, the procedure was applied in a 6th order aircraft model, 6th order doubly fed induction generator model of a wind plant and a 4th order electric circuit model which were used to evaluate the fusion of the computational intelligence paradigms and the control design method performance.The performance of the neural-genetic models are evaluated by the first and second statistics moments for the genetic algorithm, whereas the neural network is evaluated by surfaces of the energy function and of the norm of the infinity of the algebraic equation of Riccati and the results compared to the results obtained by using Schur’s Method.Acesso AbertoTeoria de controleEquação algébrica de RiccatiLQR (Regulador Linear Quadrático)RNR (Rede Neural Recorrente)Algoritmos genéticosControle inteligenteOtimizaçãoControl theoryLinear quadratic regulatorAlgebraic Riccati equationOptimizationRecurrent neural networkIntelligent controlTeseCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::ELETRONICA INDUSTRIAL, SISTEMAS E CONTROLES ELETRONICOS::AUTOMACAO ELETRONICA DE PROCESSOS ELETRICOS E INDUSTRIAISCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::ELETRONICA INDUSTRIAL, SISTEMAS E CONTROLES ELETRONICOS::CONTROLE DE PROCESSOS ELETRONICOS, RETROALIMENTACAO
