AbstractThe satellite attitude and orbit control subsystem (AOCS), that one in charge of the attitude control, can be designed with success by linear control theory if the satellite has slow angular motions and small attitude maneuver. However, for large and fast maneuvers, the linearized models are not able to represent all the perturbations due to the effects of the nonlinear terms present in the dynamics and in the actuators (e.g., saturation) which can damage the systems performance. Therefore, in such cases, it is expected that nonlinear control techniques yield better performance than the linear control techniques, improving the AOCS pointing accuracy without requiring a new set of sensors and actuators. One candidate technique for the design of AOCS control law under a large and fast maneuver is the State-Dependent Riccati Equation (SDRE). SDRE provides an effective algorithm for synthesizing nonlinear feedback control by allowing nonlinearities in the system states while offering great design flexibility through state-dependent weighting matrices. The Brazilian National Institute for Space Research (INPE, in Portuguese) was demanded by the Brazilian government to build remote-sensing satellites, such as the Amazonia-1 and CONASAT mission. In such missions, the AOCS must stabilize the satellite in three-axes so that the optical payload can point to the desired target. Currently, the control laws of AOCS are designed and analyzed using linear control techniques in commercial software. In this work, we report an open-source nonlinear satellite simulator built to analyze control laws and their stability and robustness. This satellite simulator is implemented in Java using Hipparchus (linear algebra library; which was extended in order to support the SDRE technique) and Orekit (flight dynamics framework). The initial results ratify that SDRE yields better performance in the INPEs missions. RESUMO: O subsistema de controle de atitude e órbita (AOCS), aquele responsável pelo controle de atitude, pode ser projetado com sucesso através da teoria de controle linear se o satélite tem movimentos angulares lentos e pequenas manobras de atitude. No entanto, para grandes e rápidas manobras, os modelos linearizados não são capazes de representar todas as perturbações devido aos efeitos dos termos não lineares presentes na dinâmica e nos atuadores (por exemplo, saturação), o que pode comprometer o desempenho do sistema. Portanto, nestes casos, é esperado que técnicas de controle não linear apresentem melhor desempenho que técnicas lineares, melhorando a acurácia de apontamento do AOCS sem necessitar de conjuntos adicionais de sensores e atuadores. Uma técnica candidata para o projeto do controle para grandes e rápidas manobras é a equação de Riccati dependente de estado (State-Dependent Riccati Equation; SDRE). SDRE fornece um algoritmo efetivo para a sintetização de controle baseado em realimentação (feedback control) permitindo não linearidades nos estados do sistema enquanto oferece grande flexibilidade de projeto. O Instituto Nacional de Pesquisas Espaciais (INPE) é demandado pelo governo Brasileiro para projetar e implantar satélites de sensoriamento remoto, como as missões Amazonia-1 e CONASAT. Em tais missões, o AOCS deve estabilizar o satélite em três eixos de forma que a carga ótica útil possa apontar para o alvo em solo. Atualmente, o controle do AOCS é projetado e analisado usando controle linear em software comercial. Neste trabalho, apresentamos um simulador de satélites não linear projetado para analisar técnicas de controle bem como sua estabilidade e robustez. Este simulador de satélites é implementado em Java usando-se Hipparchus (uma biblioteca de álgebra linear, que foi estendida para suportar a técnica SDRE) e Orekit (um quadro de trabalho para dinâmica de vôo). Os resultados iniciais ratificam que o SDRE oferece melhor performance para as missões do INPE.
