The recently introduced discrete power-based control (Ruderman (2024b))
reduces largely the communication efforts in the control loop when compensating
for the marginally damped or even slowly diverging output oscillations. The
control commutates twice per oscillations period (at the amplitude peaks) E
uses the measured harmonic output only. The power-based control scheme requires
the knowledge of the instantaneous frequency, amplitude, and bias parameters of
the harmonic signal. This paper extends the power-based control by the
finite-time estimation of the biased harmonics (Ahmed et al. (2022)). Also an
improved analytic calculation of the impulse weighting factor is provided. The
power-based oscillations control with online estimation of the harmonic
parameters is evaluated experimentally on the fifth-order actuator system with
a free hanging load under gravity and measurement noise.
