abstract = "When designing control systems, electrohydraulic actuators applied
to thrust vector control can represent a great challenge due to
their highly nonlinear dynamics. This work aims to study some of
the issues encountered when modelling nonlinear effects of such
actuators on the Brazilian satellite launcher VLS and how it is
possible to overcome these issues using a frequency identification
approach. Furthermore, it is shown how the use of transfer
functions can eventually mask the influence of initial conditions
on real systems. Finally, a complete nonlinear actuator model is
presented and its results are compared to Hardware-In-The-Loop
simulations.",
