Abstract. The problem of improvement of dynamic characteristics of power gyroscopic instruments is considered, the instruments serve as executive organs providing control over spatial movement of spacecraft relative to its mass center. The proposed approach is based on introduction to the system of executive electric drive a nonlinear control laws. For a modern gyrodine, the structure of digital executive electric drive build on the basis of classic linear controllers is analyzed. A universal algorithm of replacement of linear PID controller (proportional-integral-derivative controller) with a non-linear fuzzy-logic controller of PID-type is presented. An increase in accuracy and speed of operation of the gyrodine with fuzzy control is demonstrated by presented results of mathematical simulation.

Keywords: power gyroscopic complex, gyrodyne, fuzzy control
