Abstract
Prescribed-performance control (PPC) for high-power dynamics with time-varying
unknown control coefficients requires to address two open problems: a) given a
Nussbaum function, which properties hold for the power of the Nussbaum
function? b) to avoid high gains, how to design a switching gain that increases
only when the tracking error is close to violate the performance bounds? To
address the first problem, we show with a counterexample and a positive example
that only some Nussbaum functions are suited to handle time-varying unknown
control coefficients for high-power dynamics. To address the second problem, we
propose a new switching conditional inequality.
