| Resumen |
This paper presents a smooth control strategy for the regulation problem of an uncertain system, which assures uniform
ultimate boundedness of the closed-loop system inside of the zero-state neighbourhood. This neighbourhood can be made
arbitrarily small. To this end, a class of nonlinear proportional integral controllers or PI controllers was designed. The
behaviour of this controller emulates very close a sliding mode controller. To accomplish this behaviour saturation functions
were combined with traditional PI controller. The controller did not need a high-gain controller or a sliding mode controller
to accomplish robustness against unmodelled persistent perturbations. The obtained closed-solution has a finite time of
convergence in a small vicinity. The corresponding stability convergence analysis was done applying the traditional Lyapunov
method. Numerical simulations were carried out to assess the effectiveness of the obtained controller. |
