             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.",
