WitrynaFirst, a coupled linear velocity and angular velocity observer, driven by the spacecraft position and attitude measurements, is designed via the immersion and invariance (I&I) methodology. After dominating the nonlinear terms in the pose dynamics due to rotation motion by high-gain injection, the observer is shown to be exponentially convergent. Witryna19 cze 2013 · The present contribution introduces a nonlinear observer for the rotation angle and the velocities of the ball and beam system. It is based upon the Immersion and Invariance (I&I) methodology and it uses measurements of the relative rotation angle and the absolute ball position. Significant practical relevance of this contribution … Witryna27 wrz 2024 · Under the framework of Immersion and Invariance (I&I) adaptive control, a set of sufficient conditions is obtained to stabilize the concerned time-varying nonlinear systems. ...
