This paper presents the method for implementing robust control using a nominal model of an unmanned aerial vehicle (UAV). The operation of a classical controller in a nonlinear control system in the event of disturbing influences does not satisfy the specified quality criteria. This changes the aerodynamic parameters, and the system becomes unstable. To eliminate unwanted deviations in the control system of the aircraft introduced robust control. The introduction of such a correction control signal allows you to fend off all sorts of failures and disturbances that lead to uncontrolled control. Changes in the aerodynamic lift coefficients, coefficient of resistance, and moments affect the model of the object. The nominal model is calculated by calculating the coefficients with the ANSYS-CFX software and the calculation is confirmed experimentally. Errors are also modeled by this software, and the ranges of variation of each coefficient are a set of failures.
