An output feedback control law is proposed in this paper for spacecraft attitude reorientation task. Although maneuver has been widely investigated and obtained significant results, it still challenging when considering pointing constraints lacking the information of angular velocity. Firstly, potential function introduced to tackle constraints. Then, by jointly designing sign function, anti-un...

Abstract We study output reference tracking of systems with high relative degree via feedback only; this is, where the derivatives are unknown. To end, we prove that conjunction funnel pre-compensator a minimum phase system arbitrary yields same which is as well. The error between original system’s and pre-compensator’s evolves within prescribed performance funnel; moreover, known explicitly. T...

This paper deals with sampled-data control of nonlinear systems in the output feedback form. A sampled-data control strategy is proposed based on the existing control design in the continuous-time domain via output feedback. The proposed control uses the sampled output and a discrete-time implementation of filters involved. The overall stability of the system under the proposed control has been...
