Complementary filter synthesis of gyrostabilizer
Information systems, mechanics and control, 2018 This paper considers the synthesis of a complementary filter designed to determine the angular position of the gyrostabilizer platform. An engineering synthesis technique is proposed, allowing you to select filter parameters and evaluate its effectiveness. The question of the synthesis of a complementary filter in the platform is considered.
