Abstract :
The proposed modified twisting controller provides for the exact output regulation of uncertain dynamic systems with relative degree 2. The convergence rate is prescribed in advance. The fixed-time convergence is obtained as a particular case, if the transient time is uniformly bounded. An output-feedback version of the controller is presented as well.
