This paper investigates the problem of synchronizing the chaotic attitude dynamics of multiple spacecraft is investigated based on the distributed predictive control approach. Kinematic and dynamic equations are used to describe the spacecraft system according to the Modified Rodriguez Parameters representation. The respective method follows the sequential and cooperative structure of distribut...
This paper constructs a relationship between attitude and translational movement of a quadrotor, and presents a PD logic tracking control design algorithm capable of not only stabilizing attitude but also tracking a desired trajectory accurately. In contrast to conventional flight control systems, the artificial inner/outer-loop structure is eliminated via using a third-order time optimal track...
An accelerometer-array attitude-calibration method is proposed here. Being based on the compatibility of rigid-body point accelerations, this method can be applied to determine and account for the accelerometer installation errors with a high degree of accuracy. It is assumed that the number of three-axis accelerometers in the array is redundant in order to help reduce the effect of sensor nois...
