A novel smooth attitude algorithm is presented for rigid spacecraft in the presence of assigned sensor and actuator saturations, as well as external disturbances. More specifically, an analog of variable structure control law is first developed by explicitly taking into account the velocity and control constraints simultaneously. In the proposed controller, behavior of the adaptive parameter is investigated...
This paper investigates the circular formation control problem of multiple nonholonomic vehicles of unicycle type. The measurement of each vehicle is based on its local coordinate frame and the communication network among vehicles is modeled by a directed cycle graph. A distributed dynamic control law is designed by only using the local measurement of each vehicle and information of its neighbors...
