Synthesis of the Laws of Stabilization of the Short-Period Longitudinal Motion of Uavs in the Absence of Information on the Measurement of the Angle of Inclination of the Trajectory. Analytical Approach
N.E. ZUBOV, K.A. MECHKINA

The article discusses the problem of analytical synthesis of a matrix of feedback coeffi cients for stabilization of short-period longitudinal
motion in the absence of information about the angle of inclination of the trajectory. As a mathematical model of motion, a linear nonstationary
system of the third order with scalar control, i.e. with one control element, is used. The analytical synthesis of the feedback law is based
on the decomposition of the model of the initial system and the relationship between modal control by state and modal control by output
established by the results of the analytical solution for a fully given state vector using the possible, from the point of view of ensuring the
stability of motion, given and calculated values of the poles of the closed control system. With the help of the proposed approach to solving
the problem of stabilization control, a synthesis of the control laws for the output was carried out in the absence of information about the
angle of inclination of the trajectory. A hypothetical UAV was used as the object of modeling.
Keywords: short-period longitudinal motion, unmanned aerial vehicle, output control, matrix of feedback coeffi cients, analytical
synthesis.
