变质心飞行器总体布局方式研究

scheme of using an annular ring slideway instead of traditional layout of rectangular orthogonal slideway is proposed in this paper for the endoatmosphere non-spinning moving mass Actuated vehicle. First of all, the dynamic model is established based on this layout configuration by using Newton's second law and the moment of momentum theorem. Then the simplified model is derivated and proved correct by numerical simulation. Compared with the rectangular orthogonal slideway, the presence of two moving masses within this annular ring can provide a measure of redundancy and fault-protection, and also can greatly improve the control capacity of moving point masses. Finally, an optimized algorithm that minimizes the movement of the masses to obtain a desirable center of mass is proposed based on optimal control theory. This algorithm solves the slider movement possible collisions of moving masses within the annular ring sildeway.
