Abstract :
A universal finite-time-convergent controller is developed capable to control the output of any uncertain single-input-single-output system with a known permanent relative degree r. The tracking error σ is steered to zero by means of a control dependent only on σ, σ˙, ..., σ(r-1) and continuous everywhere except the set σ=σ˙=···=σ(r-1)=0. A robust output-feedback controller version provides for the tracking accuracy proportional to the sampling noise magnitude.
