Resumen
This paper proposes the use of the gain-changing non-linearity to improve the estimation of the ultimate point, which is used in many auto-tuning algorithm of PID controllers. The experiments for identification are similar to the relay feedback, therefore some well known advantages of this kind of experiments are maintained while the estimation error is significantly reduced. The identification method is evaluated with a batch of system dynamics, providing suitable results in all cases, which proves the validity of the approach.
