Abstract. This paper presents a mathematical model of a hybrid controller developed for a fixed-wing aircraft stabilization system in the pitch channel. The stabilization system model is in the block diagram form. The hybrid controller is based on an additional force on the elevator and a fuzzy controller designed to adjust the magnitude of this force. A proportional relationship between the reference input of the stabilization system and the additional force is proposed. A mathematical model of the fuzzy controller tuned using a genetic algorithm is developed. The operation of the hybrid stabilization system with the tuned parameters of the fuzzy controller is simulated. According to the simulation results, the stabilization system with the new controller structure demonstrates high performance regardless of the magnitude of the specified reference input. The stabilization system structure increases the response speed in the control loop several times compared to the classical approach.
