Resumo
Operational satellite simulators are mainly used for training operators and validating operational procedures, requiring reasonable level of fidelity in the simulated satellite telemetry. In this paper we propose the use of the subspace identification method to improve a higher level of fidelity of the model representing the CBERS-4 Electrical Power Supply Subsystem. We adopted the identification method known as n4sid to identify a state space model for real equipment of such Subsystem. To reduce the error of the identified model it is also proposed the application of two control actions, pole placement and pole placement with integral feedback. The results obtained with the identified models showed smaller errors when compared with the in-orbit CBERS-4 telemetry.
