Attitude 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 کاملCollision Avoidance in Formation Control Using Discontinuous Vector Fields
This paper presents a novel collision avoidance approach in formation control for Multi-agent Robots. The control strategy consists in the mix of attractive vector fields and repulsive vector fields based on a scaled unstable focus centered at the position of another robot, instead of the vector fields obtained from the negative gradient of repulsive potential functions. The analysis of the clo...
متن کاملCollision Avoidance Control Using Null Space Criteria
A new strategy to on-line collision-avoidance of the redundant robots with obstacles is presented. The strategy allows the use of redundant degrees of freedom such that a manipulator can avoid obstacles while tracking the desired end-effectors trajectory. The effectiveness of the proposed strategy based on null space criteria is discussed by theoretical considerations. The strategy is based on ...
متن کاملCollision Control and Collision Avoidance Using Ultrasonic Sensor
The paper proposes an intelligent collision avoidance system as a prototype, which avoids vehicle accidents and to provide a greatest security to the user in adverse or bad weather condition. Here, Ultrasonic sensor and IR sensors placed in the car, where IR sensor is used to detect the lane and avoids accident in significant manner. The vehicle state information is obtained using Ultrasonic se...
متن کاملFinite Thrust Control for Satellite Formation Flying with State Constraints
This paper considers the problem of rotating a constellation of spacecraft using on/oo thrusters such that the relative distance between the spacecraft is maintained to within a speciied tolerance. The basic idea is to resolve all of the constraints into a sphere around the desired tra-jectory of each spacecraft. As the constellation rotates, the sphere sweeps out a tube that constrains the mot...
