The aim of this course completion work is to report on the development of the prototype design of an aircraft in tilt rotor scale, to clearly and objectively cite the details of its construction, as well as to present the control techniques used to determine and guarantee the trajectory Vertically (Hover). The modeling of the system was previously developed jointly with student Rodrigo Simões Pessoa of the course of Control Engineering and Automation of the Pontifical Catholic University of Rio de Janeiro. This modeling can be observed in detail in the project final report of the course [8]. The prototype was developed using materials that are easily to obtain and very cheap, but that meet the project specifications in an acceptable way. The system is complex, presenting nonlinear and non-affine characteristics, which made the tasks of modeling and control challenging from the mathematical point of view. Simplifications were necessary to use the following control techniques: State Feedback Control using the Linear-Quadratic Regulator (LQR). We were able to mathematically control the system using the proposed techniques.
