Attitude Control without Angular Velocity Measurement: A Passivity Approach
It is well known that the linear feedback of the quar-ternion of the attitude error and angular velocity globally stabilizes the attitude of a rigid body. In this note, we show that the angular velocity feedback can be replaced by a nonlinear lter of the quaternion, thus removing the need of direct angular velocity measurement. In contrast to other approaches, this design exploits the inherent ...
متن کاملAttitude Synchronization Control in Satellite Formation Flying in the Presence of States Measurement Errors
This paper presents a novel attitude synchronization framework for tracking control of multiple identical/heterogeneous satellites in formation flying with connected communication graph. The main contribution of the paper is considering sensors' measurement error to derive control gains. Moreover, the proposed strategy need no angular velocity communication. Nevertheless, the tracking synchroni...
متن کاملEstimation of attitude via quaternion in an industrial robot
Traditionally, the automotive industry has been the largest employer of robots, but their control is inline and programmed to follow planning trajectories. In this case, in the motor's department test of Volskwagen México a semi autonomous robot is developed to generally purpose. Some critical technical problems must be solved in a number of areas, including in dynamics and control. Generally, ...
متن کاملPassive Attitude Control for Spacecraft
The stability of spacecraft attitude is studied with considering sinusoidal disturbance. A passive attitude controller without angular velocity measurement for spacecraft described by quaternion is designed. The passive controller has no information related to system parameters. So it has robustness to model error and uncertainty of model parameters. The stability of spacecraft attitude control...
متن کاملAdaptive tracking control using synthesized velocity from attitude measurements
The attitude tracking control problem of uncertain rigid spacecraft without angular velocity measurements is addressed in this paper. The adaptive control law, which incorporates a velocity-generating filter from attitude measurements, is shown to ensure the asymptotic convergence of the attitude and angular velocity tracking errors despite unknown spacecraft inertia. Simulation results are pre...
