РусскийAbstract
Introduction: The system of automatic control of the pitch angle of an aircraft is affected by numerous disturbing effects, which results in significant fluctuations in the transient process along the pitch of this system. Purpose: To transform the pitch angle control scheme and develop a fuzzy controller for it which will reduce the fluctuations of the transient process and improve the quality of the transient process. Results: An improvement in the quality of the transient process of the pitch angle control system has been achieved due to a significant reduction in fluctuations. To do this, a proportional–integrating controller has been added to the control system scheme using one of the methods of artificial intelligence – fuzzy logic. The adjustment of the fuzzy controller is carried out by converting a typical algorithm: for input linguistic variables we halve the interval of the universal set on which the membership functions are defined. Practical relevance: The correct adjustment of the fuzzy controller can significantly improve the quality of the transient process of the control system, which is affected by a large number of disturbing effects.
