Abstract

The effect of having a persistent excitation signal in a dynamic system is shown; this kind of signals accelerates the parameters convergence into their real values. The MIT rule depends on the adaptation gain and the input signal amplitude. A modification of the MIT rule is also shown, for avoiding the dependence of the input amplitude for the parameters convergence, because some systems uses small inputs as the electronic ones. As case of study, the biodegradation control of phenol into a bioreactor by using the modified MIT rule is shown.
