The purpose of this communication is to investigate the usefulness of the differential flatness control approach to solve the trajectory tracking problem for a four rotor aircraft. After introducing simplifying assumptions, the flight dynamics equations for the four rotor aircraft are considered. A trajectory tracking control structure based on a two layer(More)
In this article it is presented the influence of nanocellulose and microcellulose to mechanical and thermal properties of their composite with polyester. It used DMA method to determine the elastic and plastic behavior of polyester/nanocellulose and polyester/microcellulose composite. It is determined storage modulus, loss modulus, damping factor and glass(More)
In this paper, flight guidance dynamics are shown to be implicit differentially flat with respect to the inertial position of an aircraft. This proves the existence of a set of relations between these flat outputs and the state variables representative of flight guidance dynamics and between these flat outputs and the basic inputs to flight guidance(More)
