Stability Analysis of Three-Loop Autopilot with respect to IMU Position and C.G Variation Rate in Guided Missiles Kwon, Hyuck-Hoon; Kim, Yoon-Hwan; Park, Bong-Gyun;
Three-Loop autopilot is generally used for the acceleration control of guided missiles. Because the acceleration command to the three-loop autopilot is given as values at the center of gravity, feedback information of IMU should be obtained at the same position. However, the position of IMU might not be located at the center of gravity due to the sub-system assignment. This paper presents the stability analysis of three-loop autopilot with respect to the arbitrary position of IMU and variation rate of center of gravity. Gain and phase margins are calculated for several trim points for general anti-tank missiles.
