The article describes the techniques for determining the parameters of the unmanned aerial vehicles stabilization algorithms, which allows automating the process of choosing parameters with the given stability margin. The technique is based on the relationship between the values of the characteristic equation roots and the type of the transition function of the system under consideration. Assessment of stability margin and speed of the system is performed by the form of the transition curve for a typical input action. Using of the technique allows immediate determining the parameters of stabilization algorithms that provide the specified characteristics of transients. The problem of determining the parameters of the characteristic equation roots that allow realizing a given duration of the transient process of disturbance attack with a given accuracy and permissible overshoot is considered. An example of the technique application for analyzing a simplified model of the aircraft motion in a vertical plane is given. The obtained results are verified using the previously developed methodology for studying the stability of unmanned aerial vehicle motion based on the construction of their regions of stability
