Abstract

In an aircraft system that is in the rectilinear steady flight state ready for a longitudinal maneuver, instability, model uncertainty, and disturbances could make the maneuver impossible without the help of a controller. Considering that the dynamical equations of the aircraft are nonlinear, using a linear controller designated based on linearization at the equilibrium of the point may not be entirely efficient. Therefore, using non-linear controllers is of utmost importance. The present study aimed to design a controller using the gain scheduling method. Designing the gain scheduling-based controller was performed in two stages. Initially, linear controllers were developed, which were the controlling components of gain scheduling. The second stage involved planning in order to determine the criteria based on which one of the linear controllers was in the closed loop. The required linear controllers were selected through optimal control methods. In order to verify the number and location of the linearized points and criteria for using the linear controllers, the concepts of Stability Margin and v-gap metric were applied. Furthermore, longitudinal maneuver, which is requested as a command or a base signal in the rectilinear steady flight state, was considered as the rotational constant value for the Pitch angle. According to the results, combining the nonlinear gain scheduling controller and a nonlinear system in a closed loop could contribute to the desired longitudinal maneuver.
