To avoid trapped in undesirable local minimum, some adaptive search algorithms have been devised intending to achieve the global optimum or sub-optimum with adaptive search patterns.
It has been suggested that the reduction of end-diastolic volume might be the undesirable consequence of an adaptive mechanism of stiff myocardium, in an effort to compensate for poor contractility by increased pressure during experimental cardiomyopathy [ 22].
To control the undesirable chaos in PMSM, an adaptive dynamic surface control (DSC) law is first designed, which overcomes the problem of "explosion of terms" associated with the traditional backstepping design procedure by introducing first-order low-pass filters.
Afterwards, a Lyapunov based approach is proposed for the robust adaptive suppression of the undesirable vibrations in the finite time.
Besides, in order to further minimize the undesirable steady-state error, the frequency adaptive control was adopted without using any additional circuits.
We build defenses to adapt to undesirable elements of our early environment, but when we grow up and are in a new situation as adults, these behaviors and patterns are often no longer adaptive.
Weeds have shown a very robust and adaptive nature that renders them undesirable plants in agriculture.
One initial response is to see these adaptive hypotheses as just "excusing" undesirable behavior so we don't have to try to change it.
Moreover, FGF21 reduces physical activity and promotes torpor in Fgf21 transgenic mice: a favorable adaptive response to starvation, but an undesirable outcome in the context of obesity (Inagaki et al. 2007).
Since, as stated earlier, it is necessary to continuously or frequently perform tracking of frequency and channel state, the lengthy adaptive iteration process, which is time-consuming, should be highly undesirable.
